We investigate the long-term relationship between an organization's quality management practices and process-level performance. Further, we examine whether availability of organizational slack over the study interval interferes with the relationship between quality practices and process performance. Organizational slack consists of the available and accessible resources in an organization; we focus here on unabsorbed slack in the form of financial resources. We investigate the quality practices of U.S. general acute care hospitals, measured by their depth of implementation of practices characterizing a total quality management system, and use them to predict process performance related to four medical conditions. Analysis reveals differing effects that are dependent on hospital slack conditions. In hospitals with high slack, quality practices significantly predict three of four studied process performance measures. In contrast, in hospitals with low slack, quality practices predict only one of the four process performance measures, while other factors outweigh the effects of quality practices. This study lends support to management taking a long-term perspective related to implementation of quality management systems, and highlights the relevance of slack conditions in garnering the benefits of such systems. © 2011 Elsevier B.V.

The Beacon Sill, a member of the Jurassic Ferrar group of the Transantarctic Mountains, South Victoria Land, is a 150 m thick tholeiitic diabase intrusion. Uniform on a field and macroscopic scale, it displays chemical and textural variability indicative of a sustained and complex history of emplacement and differentiation. Emplacement of the sill consisted of at least two, and probably four, discrete massive injections of magma, each averaging ∼35 m thick, over a time span of ∼100 years. The final injection event is marked by a 30 m thick interval of significantly finer-grained rock at the sill center. These fine-grained textures can be successfully reproduced by combining the results of thermal and crystal growth models, but only if the sill was a multiple intrusion. With the exception of a minor reinjection event captured in the chilled margin of the sill, earlier reinjection events are not evident texturally, most probably because of textural overprinting during prolonged cooling after initial crystallization. The dominant process involved in the post-emplacement differentiation of the Beacon Sill was compaction-driven redistribution of interstitial liquid. Transfer of residual liquid from the compacting lower solidification front to the dilating upper solidification front resulted in characteristic chemical and mineralogical effects, such as the depletion of the lower half of the sill and the enrichment of the upper half of the sill in incompatible elements (e.g. TiO2, Zr) and modal granophyre. Based on thermodynamic models, most of the compaction occurred at a crystallinity of roughly 33%. Geochemical profiles are distinctly segmented, suggesting that the sill was repeatedly split and reinjected with fresh magma near the center after compaction had redistributed the interstitial liquid within the partially solidified magma. The recognition of evidence for reinjection and compaction in a macroscopically uniform, relatively quickly cooled sill suggests that these processes may be common in the construction of sills and other mesoscale igneous intrusions in general. © The Author 2012.

Canadian diamonds are marketed as "ethical" alternatives to notorious "blood diamonds". This paper analyzes the specific matrices through which ethical consumption as a discourse is being mobilized to sell diamonds. I argue that consumption operates as a system of social signification in which consuming subjects are positioned as moral subjects. Moreover, I argue that historically accumulated symbolic power, in the form of imagined geographies of benevolent colonialism in the Canadian North versus the exploitation of "dark" Africa, pristine, "white" northern landscapes, modernization via commodity production, and national identity, creates the very field of meaning within which the consuming subject is positioned. The ethicalization of Canadian diamonds also has important normative implications both in terms of the cultural politics of ethical consumption and social and environmental justice in the Canadian North. © 2012 The Author.

Eating Behaviors | Year: 2011

This study examined health-related quality of life in relation to psychosocial variables associated with eating disorders. A sample of 266 women and 114 men from a Midwestern university completed questionnaires asking about both generic and eating disorder-specific health-related quality of life, as well as body dissatisfaction, objectified body consciousness, internalization of sociocultural ideals, and restrained eating. Results revealed that women reported significantly higher levels of psychosocial risk variables than men. In addition, for women, all but one of the psychosocial risk variables was found to be associated with lower quality of life. Gender moderated the relationship between quality of life and objectified body consciousness, but not the other psychosocial risk variables. Finally, comparisons between a generic and an eating disorder-specific quality of life scale revealed that the eating disorder-specific scale had higher sensitivity for use in a college student population. These results suggest that women who are at higher risk for developing an eating disorder suffer from lower quality of life, and that eating disorder-specific quality of life scales are useful in understanding women and men in a general population. © 2011 Elsevier Ltd.

Mounting evidence suggests that vitamin D deficiency could be linked to several chronic diseases, including cardiovascular disease and cancer. The purpose of this study was to examine the prevalence of vitamin D deficiency and its correlates to test the hypothesis that vitamin D deficiency was common in the US population, especially in certain minority groups. The National Health and Nutrition Examination Survey 2005 to 2006 data were analyzed for vitamin D levels in adult participants (N = 4495). Vitamin D deficiency was defined as a serum 25-hydroxyvitamin D concentrations ≤20 ng/mL (50 nmol/L). The overall prevalence rate of vitamin D deficiency was 41.6%, with the highest rate seen in blacks (82.1%), followed by Hispanics (69.2%). Vitamin D deficiency was significantly more common among those who had no college education, were obese, with a poor health status, hypertension, low high-density lipoprotein cholesterol level, or not consuming milk daily (all P < .001). Multivariate analyses showed that being from a non-white race, not college educated, obese, having low high-density lipoprotein cholesterol, poor health, and no daily milk consumption were all significantly, independently associated with vitamin D deficiency (all P < .05). In summary, vitamin D deficiency was common in the US population, especially among blacks and Hispanics. Given that vitamin D deficiency is linked to some of the important risk factors of leading causes of death in the United States, it is important that health professionals are aware of this connection and offer dietary and other intervention strategies to correct vitamin D deficiency, especially in minority groups. © 2011 Elsevier Inc.

Just as volcanoes have alternating periods of eruption and repose, igneous intrusions can also have alternating periods of injection and crystallization. This study will provide a better understanding of the emplacement process and its effects in intrusive systems, specifically in mafic sills. The study will identify the diagnostic physical and chemical signatures of magma reinjection into a partially crystalline system and the specific textural characteristics of a reinjection horizon that can be used to determine its timing and thermal conditions. Diagnostic criteria for recognizing reinjections in mafic systems will allow this process to be positively identified in other intrusions and will place important constraints on models for magma chamber formation and evolution. In addition, the data to be developed (texture, composition, and mineralogy profiles) will be widely distributed as a resource for developing and testing petrologic hypotheses, and for recognizing additional processes beyond those specifically addressed in this study.

The primary goal of this study is to define the detailed signature of reinjection events using a continuous drill core profile through a diabase sill (the Black Sturgeon sill) from Nipigon, Ontario. Petrographic data will include modal mineralogy, textures (crystal size distributions), and fabric (alignment factor). Geochemical data will include bulk-rock major and trace-element chemistry and mineral compositions. Preliminary results have been used to tentatively identify the positions and effects of several reinjection events in the Black Sturgeon sill. This project will document the fine-scale variations around these sites and locate and characterize other potential reinjection zones. These textural and compositional variations will provide a set of discrete criteria that can be used to demonstrate and document the existence of reinjection horizons in magmatic systems. Numerical cooling models will then be integrated with textural observations and with MELTS modeling to provide quantitative constraints on the emplacement history of the Black Sturgeon sill, including the timing and spatial distribution of the individual replenishment events.

Primates are distinguished from most other mammals by a trend toward midfacial reduction, most notably seen in the reduced snout of monkeys, apes, and humans. This study uses a novel developmental approach to test whether midfacial reduction of the skull in primates is a byproduct of growth of neighboring structures (e.g., eyes and teeth). For example, does selection for a precocious visual nervous system fundamentally affect midfacial patterns of growth? Do proportionately large deciduous maxillary teeth and their successors have transient or lasting effects on development of paranasal spaces of the maxilla? To answer these questions, cadaveric samples from over seventy specimens (including 20 species of primates) will be studied. Specimens of different postnatal ages will be studied using an innovative combination of high-resolution computed tomography (CT) and microscopic study of decalcified samples. The result is a novel approach for mapping regions of bone deposition and resorption in three dimensions. The project will create unique three-dimensional growth maps of primate skulls in relation to functional units of the head (eyes, nasal airways, teeth). Three-dimensional skull form and growth maps will then be compared among primates that differ in the extent to which the eyes are convergent (forward-facing). Indirect influences on neural and dental development, such as gestation length and diet, will also be used as variables.

The broader implications of the study include a web-based atlas and digital archive of histological and CT images from the specimens. The interactive online atlas will be developed as a resource for anatomists, who will benefit from animal models for aspects of human development, and primatologists, who will benefit from the resource on development of primates. In addition, animations which highlight the importance of growth mechanisms for evolutionary adaptation will be created and made available to advanced K-12 students and their teachers as online educational tools.
