Estimation of parameters in latin squares and graeco-latin squares with missing observations

We show that if in an additive model with p-2 MOLS if one omits up to p-1 observations from the same row, the same column or which correspond to the same letter in any of the squares all effects are estimable. On the other hand with only two missing observations not from the same row, the same column or corresponding to the same letter in any of the squares one degree of freedom is lost for each set of effects.     

Analysis of binary data in the randomized complete block design

The technique proposed by Shah and Claypool (1984) is extended here for the randomized complete block design with one binary observation per cell. In addition, it provides an al- ternative derivation of the distribution of Cochran's Q sta- tistic which is straightforward.     

On the optimality of the generalized room squares

Using a model given by Archbold and Johnson (1958) it is shown that the generalised Room square design is universally optimal for the estimation of the treatment effects. Further, if the variety-block design in a generalised Room square design is a BIBD, this design is also universally optimal for the estimation of the varietal effects.     

戴·赫·劳伦斯短篇小说中的“支离人”研究

劳伦斯在短篇小说中创作了"支离人"这种特有的艺术形象。本文在探讨支离人的内涵、成因和艺术效果的基础上指出,现代性特征之一的断裂导致了西方人支离破碎的生存状态。劳伦斯塑造支离人目的并非单纯地描绘人们存在与虚无的对立,而是为存在找到基点和支撑。     

Athletes’ Perceptions of National Collegiate Athletic Association–Mandated Sickle Cell Trait Screening: Insight for Academic Institutions and College Health Professionals

Abstract

Objective: The study objective was to explore athletes’ perspectives of National Collegiate Athletic Association (NCAA)–mandated sickle cell trait (SCT)–screening policy by examining race- and gender-related differences in athletes’ perceptions regarding risk of having SCT and concern about loss of playing time. Participants: Participants were 259 athletes at a southeastern United States campus during April–August of 2010. Methods: Athletes completed a 21-question survey. Results: The majority of athletes (81.7%) perceived that they would have a high level of concern if found to carry the SCT. African Americans were 9.07 times more likely than Caucasians to perceive risk of having the SCT. The majority of athletes disagreed (38.4%) or did not know (50.8%) if they would lose playing time related to carrying the SCT. Conclusion: Campus health professionals must be aware of athletes’ perspectives on NCAA's SCT screening so that athletes are not unnecessarily subjected to stress or harm.     

The unbearable proximity of the Orient: Political religion,multiculturalism and the retrieval of South Asian identities

The phenomenon of religion -- specifically its recent return as 'political religion', and its seeming incompatibility with the demands of multiculturalism -- continues to be a vexed issue in attempts to rethink retrievals of South Asian identity beyond a neo-colonial imaginary. This move 'beyond' has routinely followed a deconstruction of the 'religious effects' of Orientalism whose conceptual matrix, some argue, can be located in Hegel's writings on history and religion. Taking its cue from Derrida's enigmatic remark -- 'what if religio remained untranslatable?' -- this paper re-examines Hegel's writings on India, revealing the workings of an ontotheological matrix which underpins not only the recent resurgences of religious nationalism or political religion in South Asia and the South Asian diaspora, but also, paradoxically, the secular frameworks of contemporary multiculturalism and anti-imperialist critique. Despite sharing the same onto-theological matrix, these bastions of secular modernity still refuse to recognise that retrievals of religious identity might constitute a significant reorientation of the political, instead continuing to put into play a series of well rehearsed distancing techniques which serve merely to sanitize the 'religious effects' of the Orient.     

Increased Focus on the Mouth Among Infants in the First Year of Life: A Longitudinal Eye‐Tracking Study

This study examines face‐scanning behaviors of infants at 6, 9, and 12 months as they watched videos of a woman describing an object in front of her. The videos were created to vary information in the mouth (speaking vs. smiling) and the eyes (gazing into the camera vs. cueing the infant with head turn or gaze direction to an object being described). Infants tended to divide their attention between the eyes and the mouth, looking less at the eyes with age and more at the mouth than the eyes at 9 and 12 months. Attention to the mouth was greater on speaking trials than on smiling trials at all three ages, and this difference increased between 6 and 9 months. Despite consistent results within subjects, there was considerable variation between subjects. This raises the question of whether a developmental “norm” of face scanning in infancy ought to be pursued. Rather, these data add to emerging evidence suggesting that individual differences in face scanning might reliably predict aspects of later development.     

Testing equality of several exponential distributions

Roy's union-intersection principle is used to develop a test procedure to test the equality of scale parameters of several exponential distributions. Upper five and one percent values of the test statistic for two and three exponential distributions are tabulated and an illustrative simulated example is qiven.     

Analysis of designs with two-way elimination of heterogeneity

We consider designs for which the treatment association matrices for the row design and for the column design commute. For these designs it is shown that the usual procedures of combined estimation yield unbiased estimates of treatment differences. For an important special class of designs a procedure of combined estimation is proposed which assures improvement over the estimates obtained from the interaction analysis.
