Orthogonal block designs in mixture experiments have been extensively studied by various authors. Aggarwal et al. [M.L. Aggarwal, P. Singh, V. Sarin, and B. Husain, Mixture designs in orthogonal blocks using F-squares, METRON – Int. J. Statist. LXVII(2) (2009), pp. 105–128] considered the case of components assuming the same volume fractions and obtained mixture designs in orthogonal blocks using F-squares. In this paper, we have used the class of designs presented by Aggarwal et al. and have obtained D-, A- and E-optimal orthogonal block designs for four components in two blocks for Becker's mixture models and K-model, respectively. Orthogonality conditions for the considered models are also given. 相似文献

We study distributional properties of generalized order statistics (gos) related by a random shift or scaling scheme in the continuous and discrete case, respectively. In the continuous case, we obtain new characterizations of distributions relating non-neighbouring gos extending some results given in the literature for the neighbouring cases. On the other hand, in the discrete case, we investigate the existence and uniqueness of a discrete parent distribution supported on the integers whose gos are related by a random translation. 相似文献

We examine the sizes and powers of three tests of convergence of Markov Chain Monte Carlo draws: the Kolmogorov–Smirnov test, fluctuation test, and Geweke's test. We show that the sizes and powers are sensitive to the existence of autocorrelation in the draws. We propose a filtered test that is corrected for autocorrelation. We present a numerical illustration using the Federal funds rate. 相似文献

This paper analyses impression management (IM) during the global financial crisis (GFC). It examines the differences in multiple textual characteristics and attributions between a highly positive performance period (2002–2007) and the GFC period (2008–2012), within the setting of Spain, where these two economic cycles were extreme. In contrast to previous research, companies' extreme poor performance in our sample is driven by an exogenous event. The findings do not show clear evidence of IM based on textual characteristics specifically linked to the GFC. Companies tried not to use overt IM and, to some extent, tried to clarify the impact of the crisis on performance. They were under great scrutiny and probably preferred to tell a more careful story. However, a general pattern of IM was still present during the GFC in the form of consistent positive attributions, favourable benchmarks and enhancement practices. In essence, the crisis did not fully stop IM practices, but rather influenced the way IM was produced. Overall, our results show that IM was lower during the GFC than in the case of poor performance in normal macroeconomic conditions found by previous literature. The results also show that the narratives of firms in the finance and real estate sectors were the most reactive to the GFC, probably linked to their key role in the crisis. 相似文献

Recent scholarship in the sociological subfields of culture and immigration offers several promising directions for studying how people experience the world in embodied ways and move through and across boundaries. Yet, the lack of overlap between fields has left numerous theoretical angles unexplored. In this review, I consider the limited existing scholarship at the intersection of migration and the senses. I discuss literature on the role of sensation during three critical moments of migration: movement, encounter, and return. These moments highlight the sensorially dislocating nature of travel, the felt politics of inclusion and exclusion, and the transporting power of embodied memories. These works dive deep into the everyday realities of bodies on the move that public and academic discourse has previously ignored. I conclude by briefly outlining exciting new directions to expand work connecting migration and the senses and suggest that we begin to explore globalized migrant sensibilities. 相似文献

BackgroundPrivacy is related to a person’s sense of self and the need to be respected and it is a key factor that contributes to women’s satisfaction with their birth experiences.AimTo examine the meaning of privacy for Jordanian women during labour and birth.MethodA qualitative interpretive design was used. Data were collected through face-to-face semi-structured interviews with 27 Jordanian women. Of these women, 20 were living in Jordan while seven were living in Australia (with birthing experience in both Jordan and Australia). Thematic analysis was used to analyse the data.ResultsThe phrase ‘there is no privacy’ captured women’s experience of birth in Jordanian public hospitals and in some private hospital settings. Women in public hospitals in Jordan had to share a room during their labour with no screening. This experience meant that they were, “lying there for everyone to see”, “not even covered by a sheet” and with doctors and others coming in and out of their room. This experience contrasted with birth experienced in Australia.ConclusionsThis study explicates the meaning of privacy to Jordanian women and demonstrates the impact of the lack of privacy during labour and birth. Seeking a birth in a private hospital in Jordan was one of the strategies that women used to gain privacy, although this was not always achieved. Some strategies were identified to facilitate privacy, such as being covered by a sheet; however, even simple practices are difficult to change in a patriarchal, medically dominated maternity system. 相似文献

The well‐being of children in informal kinship care and their caregivers is a growing concern globally. This study explored the lived experiences of 23 kin caregivers raising children left behind in rural Northeast China while their migrant parents worked and lived in cities. The findings show that the expected authority and responsibility caregivers carry sometimes conflict with their social role of being children's grandparents. Caregivers' feelings about and understandings of these roles are shaped through their social interactions in local communities. In view of their situation and caregivers' self‐conscious attitudes towards utilizing local resources' future formal service provision and social support should take caregivers' viewpoints into account. These views are embedded in and shaped by their rural living context and relationships with community members who influence caregivers' perceptions and child rearing practices. 相似文献

公民参与公共服务的有序性和有效性并非直接相关,可以从有序性和有效性两个维度分析公民参与及其治理效能的关系.为提升治理效能,以程序性规则为核心的制度设计能更为充分地保障公民有序有效参与公共服务,实现公民与政府之间的良性互动与有序合作.基于全过程民主、程序性权利和共同体秩序等公民参与的程序性价值维度考量,再以环境保护领域中的公民参与为例,从公开公示机制、意见表达机制、回应吸纳机制、监督评价机制和责任追究机制等方面构建公民全过程参与制度,并探索公民参与的方法和策略.通过公民参与的程序性价值内化、方法创新与技术转型来推进治理体系和治理能力现代化. 相似文献

ABSTRACTDo right-wing women hold unique policy priorities from that of left-wing women and right-wing men? And do right-wing women legislators represent the priorities of right-wing citizens? Right-wing women share unique gendered socialization experiences with left-wing women, but their ideology informs values and attitudes critical to policy preference formation. Political representation theories suggest that women legislators should hold distinct incentives to represent female constituents. However, institutional theories suggest right-wing women legislators may face different incentives that limit the extent to which they represent right-wing female constituents. To evaluate our expectations, we leverage survey data from the Latin American Public Opinion Project and the Parliamentary Elites of Latin America. We demonstrate how right-wing women citizens differ from left-wing women citizens across a range of policy priorities. Then, we evaluate elite priorities for these same policy issues. We find little evidence for policy priority congruency between women citizens and women legislators on the right. 相似文献

Studies of brain size of children classified with ADHD appear to reveal smaller brains when compared to ‘normal’ children. Yet, what does this mean? Even with the use of rigorously screened case and control groups, these studies show only small, average group differences between children with and without an ADHD classification. However, academic textbooks used in the Netherlands often portray individual children with an ADHD classification as having a different, malfunctioning brain that necessitates medical intervention. This conceptualisation of ADHD might serve professional interests, but not necessarily the interests of children. 相似文献
