Where Would I Be Without You, the first and only poetry recording from Olivia Records, offers a glimpse into the powerful friendship and artistic collaboration between poets Pat Parker and Judy Grahn. Grahn and Parker met in Oakland, California in 1970, beginning an artistic collaboration and a powerful friendship that endured through Parker's death in 1989. Grahn's and Parker's work spread the good news of poetry; they were integral to how we lesbians imagined our voices in the world. The articles in this special issue reconsider and pay tribute to their work.  相似文献

This paper draws on archival research and theoretical work to articulate the specific histories, processes, and structures of primitive accumulation in British Columbia. Such processes of accumulation appear differently here than in the comparably more well-theorized contexts of imperial colonialisms. As we highlight the agents and infrastructures of dispossession, our research also aims to foreground the importance of agents and infrastructures of resistance. Different dispossessions generate different antagonisms, and we argue that Indigenous subjects are situated antagonistically to capital not only as laborers partially or wholly subsumed into capitalist social relations, but as Indigenous peoples as such, whose Indigeneity has been ‘in the way’ of development from the 1850s onward. Private property requires before all else the deterritorialization of those whose relations with the land do not revolve around its commodification. Violence against Indigenous nations, and especially Indigenous women, is not incidental to capitalist development but is a prerequisite to capitalist subsumption in the settler-colonial context. In requiring the death of either Indigeneity or the person, capital constitutes Indigenous struggle as an antagonist, interrupting both the subsumption of labor and the circulation of capital (even as such struggles may also self-constitute themselves in a variety of ways).  相似文献

A number of studies have suggested breastfed infants have improved bonding and attachment or cognitive development outcomes. However, mechanisms by which these differences might develop are poorly understood. We used maternal time use data to examine whether exclusively breastfeeding mothers spend more time in close interactive behaviors with their infants than mothers who have commenced or completed weaning. Mothers (188) participating in a time use survey recorded infant feeding activities for 24 h over a 7 day period using an electronic device. Tracking was conducted at 3, 6, and 9 months postpartum. Data was collected for maternal activities including infant feeding and time spent in emotional care. The mothers of exclusively breastfed infants aged 3–6 months fed them frequently and total time spent in breastfeeding averaged around 17 h a week. Maternal time spent in emotional care was also substantial, and found to correlate positively with time spent breastfeeding. Exclusively breastfed infants received greatest amounts of emotional care from their mother, and exclusively formula fed infants the least. Mixed fed infants received more emotional care time than formula fed infants, but less than fully breastfed infants. These findings may help explain the differential cognitive developmental outcomes reported in the medical literature for breastfed and non breastfed infants.  相似文献

The second part of this paper deals with the legal basis of medico-statistical data, and shows the type of report made by Medical Officers of Health and by private practitioners to the Norwegian Central Statistical Office. These reports deal with infectious diseases, with certain types of mental disease, and certain special diseases like tuberculosis. The system of classifying causes of death is also explained. Other sections deal with hospital and morbidity statistics and statistics obtained from recruiting authorities.  相似文献

We consider the properties of the trimmed mean, as regards minimax-variance L-estimation of a location parameter in a Kolmogorov neighbourhood K() of the normal distribution: We first review some results on the search for an L-minimax estimator in this neighbourhood, i.e. a linear combination of order statistics whose maximum variance in Kt() is a minimum in the class of L-estimators. The natural candidate – the L-estimate which is efficient for that member of Kt,() with minimum Fisher information – is known not to be a saddlepoint solution to the minimax problem. We show here that it is not a solution at all. We do this by showing that a smaller maximum variance is attained by an appropriately trimmed mean. We argue that this trimmed mean, as well as being computationally simple – much simpler than the efficient L-estimate referred to above, and simpler than the minimax M- and R-estimators – is at least “nearly” minimax.  相似文献

One classical design criterion is to minimize the determinant of the covariance matrix of the regression estimates, and the designs are called D-optimal designs. To reflect the nature that the proposed models are only approximately true, we propose a robust design criterion to study response surface designs. Both the variance and bias are considered in the criterion. In particular, D-optimal minimax designs are investigated and constructed. Examples are given to compare D-optimal minimax designs with classical D-optimal designs.  相似文献

In recent years there has been a renewed interest in psychodynamic ideas within the family therapy literature. While some authors have explored the usefulness of psychodynamic concepts in the systemic context (Byng-Hall, 1995; Flaskas, 1993, 1996; Luepnitz, 1988, 1997), others have argued that psychodynamic models of family therapy should be given more credence in systemic work with families (Guttman, 1991). This paper describes Object Relations Family Therapy (ORFT), a psychoanalytic model of family therapy, in plain English in order to minimise the obscurity of some of the existing terminology and to emphasise the utility of more contemporary formulations. ORFT addresses the interface between psychoanalytic and systemic theories. It offers a way of conceptualising complex family dynamics at both the interpersonal and intrapsychic levels. It also integrates an understanding of nonverbal, unstated and often implicit processes in its formulation of problem development. The unique contribution of ORFT is elaborated using a clinical example.  相似文献
