The Pushcart Prize, established in 1976, has a well-deserved reputation for highlighting the best in small press publication. The authors examined the first thirty volumes, 1976/1977 through 2006, to identify attributes of the items included in each volume and placed the volumes into five time periods of six volumes each to facilitate trend analysis. In order to identify the most productive publications, titles that had fewer than four selections in the thirty volumes and did not appear in at least two time periods were eliminated. The authors examined: press status as independent or affiliated, state and region where published, and type of work (poetry or other). Finally, highly productive titles were reviewed in WorldCat to determine how frequently these were held in the United States.California, Massachusetts, New York, and Ohio have a continuing, substantial presence in the Prize volumes. Most of the publications included were still active and were affiliated with a larger institution. The three small press titles appearing most frequently were Ploughshares, Paris Review, and American Poetry Review. The Pushcart Prize selections most frequently listed in WorldCat were the Hudson Review, the Paris Review, and the American Poetry Review. Each is held by more than eight hundred U.S. libraries. 相似文献

Summary. To investigate the variability in energy output from a network of photovoltaic cells, solar radiation was recorded at 10 sites every 10 min in the Pentland Hills to the south of Edinburgh. We identify spatiotemporal auto-regressive moving average models as the most appropriate to address this problem. Although previously considered computationally prohibitive to work with, we show that by approximating using toroidal space and fitting by matching auto-correlations, calculations can be substantially reduced. We find that a first-order spatiotemporal auto-regressive (STAR(1)) process with a first-order neighbourhood structure and a Matern noise process provide an adequate fit to the data, and we demonstrate its use in simulating realizations of energy output. 相似文献

The basic assumption underlying the concept of ranked set sampling is that actual measurement of units is expensive, whereas ranking is cheap. This may not be true in reality in certain cases where ranking may be moderately expensive. In such situations, based on total cost considerations, k-tuple ranked set sampling is known to be a viable alternative, where one selects k units (instead of one) from each ranked set. In this article, we consider estimation of the distribution function based on k-tuple ranked set samples when the cost of selecting and ranking units is not ignorable. We investigate estimation both in the balanced and unbalanced data case. Properties of the estimation procedure in the presence of ranking error are also investigated. Results of simulation studies as well as an application to a real data set are presented to illustrate some of the theoretical findings. 相似文献

The paper deals with the problem of using contours as the basis for defining probability distributions. First, the most general probability densities with given contours are obtained and the particular cases of circular and elliptical contours are dealt with. It is shown that the so-called elliptically contoured distributions do not include all possible cases. Next, the case of contours defined by polar coordinates is analyzed including its simulation and parameter estimation. Finally, the case of cumulative distribution functions with given contours is discussed. Several examples are used for illustrative purposes. 相似文献

The problem considered is that of finding an optimum measurement schedule to estimate population parameters in a nonlinear model when the patient effects are random. The paper presents examples of the use of sensitivity functions, derived from the General Equivalence Theorem for D-optimality, in the construction of optimum population designs for such schedules. With independent observations, the theorem applies to the potential inclusion of a single observation. However, in population designs the observations are correlated and the theorem applies to the inclusion of an additional measurement schedule. In one example, three groups of patients of differing size are subject to distinct schedules. Numerical, as opposed to analytical, calculation of the sensitivity function is advocated. The required covariances of the observations are found by simulation. 相似文献

This study examines the emergence of concurrent correlates of infant pointing frequency with the aim of contributing to its ontogenetic theories. We measured monthly from 8 to 12 months infants' (N = 56) index-finger pointing frequency along with several candidate correlates: (1) family socioeconomic status (SES), (2) mothers' pointing production, and (3) infants' point following to targets in front of and behind them. Results revealed that (1) infants increased their pointing frequency across age, but high-SES infants had a steeper increase, and a higher pointing frequency than low-SES infants from 10 months onward, (2) maternal pointing frequency was not associated with infant pointing frequency at any age, (3) infants' point following abilities to targets behind their visual fields was positively associated with their pointing frequency at 12 months, after pointing had already emerged around 10 months. Findings suggest that family SES impacts infants' pointing development more generally, not just through maternal pointing. The association between pointing and following points to targets behind, but not in front, suggests that a higher level of referential understanding emerges after, and perhaps through the production of pointing. 相似文献

This paper contributes to ‘visiting friends and relatives’ (VFR) discussions within migration and diaspora literatures by proposing a closer theorization of religious mobilities through the conceptual framework of ‘diasporic pilgrimage’. It advances VFR thinking by considering religion as a productive analytical category to interrogate relationships between people and place which sustain and constitute diasporic connection and attachment. This will be explored through the experiences and encounters of Palestinian–Jordanian Christians undertaking visits to places of religious and relational significance across Israel and/or Palestine from Jordan. Through an exploration of ethnographic data collected amongst diasporic Palestinian Christians living in Jordan, diasporic pilgrimage will be theorized as a localized process critically engaging with everyday facets of familiarity and regularity. This will revolve around three main elements of diasporic pilgrimage: translocal connections, temporalities and power geometries which constitute visits from Jordan and the so-called ‘Holy Land’ a diasporic form of religious mobility. 相似文献

We examined associations between hope as an internal asset that supports positive youth development, and growth trajectories of three critical consciousness components. Using five waves of data collected over the course of high school (N = 618), we modeled growth trajectories of awareness of inequity (critical reflection), a sense of agency about taking sociopolitical action (critical agency), and behaviors targeting systems of oppression (critical action). Hope was highest among those with high trajectories of critical agency and critical action. Clear associations with hope emerged at the last time point for critical reflection, suggesting that sustained growth in critical reflection is associated with hope. When supporting the critical consciousness development of youth of color, concurrent support for hope may be instrumental. 相似文献

Across a range of countries, analysts have found that adaptations to the COVID-19 pandemic often exacerbated previously existing labor inequalities between men and women in formal employment markets and households. This has been especially true for mothers with children in their households. Drawing on decades of sociological and feminist scholarship on labor, we suggest the following three strategies to strengthen ongoing research concerning pandemic-induced reorganizations of gendered labor. First, ongoing research should expand considerations of gendered labor to account for more types of work and workers. Second, initial findings should be extended through the continued utilization of diverse methodologies to better account for the ambivalent experiences and meanings associated with emergent reorganizations of gendered work during the pandemic. Finally, ongoing research should pursue intersectional analyses of gendered labor that are sensitive to the complex dynamics of place and time. By expanding and strengthening considerations of gendered labor in these manners, ongoing analyses could generate more comprehensive, precise findings that better guide policy interventions meant to address the gendered inequities being sharpened by the pandemic. Foundational theoretical understandings of gendered labor and its associated inequalities could also be extended. 相似文献
