'In a Moment of Brilliance': Heidegger's Horsemen, HIGH NOON and the Existential Sentiment of 'Westerns'

By evidence and common consent, great 'western' movies are mythical encompassing a Weltanschauung that has engaged viewers within diverse cultures for over a century. Questions recur, however. What makes them so? and why have they proven so enticing to male viewers in particular? Within this essay I and Barbara Hehner address those questions, attending to the design of HIGH NOON as exemplary

Factors Related to Self-Care in Heart Failure Patients According to the Middle-Range Theory of Self-Care of Chronic Illness: A Literature Update

Purpose of the Review As described in the theory of self-care in chronic illness, there is a wide range of factors that can influence self-care behavior. The purpose of this paper is to summarize the recent heart failure literature on these related factors in order to provide an overview on which factors might be suitable to be considered to make self-care interventions more successful. Recent Findings Recent studies in heart failure patients confirm that factors described in the theory of self-care of chronic illness are relevant for heart failure patients. Summary Experiences and skills, motivation, habits, cultural beliefs and values, functional and cognitive abilities, confidence, and support and access to care are all important to consider when developing or improving interventions for patients with heart failure and their families. Additional personal and contextual factors that might influence self-care need to be explored and included in future studies and theory development efforts

Oxytocin in pregnancy and the postpartum: relations to labor and its management.

The purpose of this study was to examine variations in endogenous oxytocin levels in pregnancy and postpartum state. We also explored the associations between delivery variables and oxytocin levels. A final sample of 272 mothers in their first trimester of pregnancy was included for the study. Blood samples were drawn during the first trimester and third trimester of pregnancy and at 8 weeks postpartum. Socio-demographic data were collected at each time point and medical files were consulted for delivery details. In most women, levels of circulating oxytocin increased from the first to third trimester of pregnancy followed by a decrease in the postpartum period. Oxytocin levels varied considerably between individuals, ranging from 50 pg/mL to over 2000 pg/mL. Parity was the main predictor of oxytocin levels in the third trimester of pregnancy and of oxytocin level changes from the first to the third trimester of pregnancy. Oxytocin levels in the third trimester of pregnancy predicted a self-reported negative labor experience and increased the chances of having an epidural. Intrapartum exogenous oxytocin was positively associated with levels of oxytocin during the postpartum period. Our exploratory results suggest that circulating oxytocin levels during the third trimester of pregnancy may predict the type of labor a woman will experience. More importantly, the quantity of intrapartum exogenous oxytocin administered during labor predicted plasma oxytocin levels 2 months postpartum, suggesting a possible long-term effect of this routine intervention, the consequences of which are largely unknown

The GALEX Arecibo SDSS Survey. VIII. Final Data Release -- The Effect of Group Environment on the Gas Content of Massive Galaxies

We present the final data release from the GALEX Arecibo SDSS Survey (GASS), a large Arecibo program that measured the HI properties for an unbiased sample of ~800 galaxies with stellar masses greater than 10^10 Msun and redshifts 0.025<z<0.05. This release includes new Arecibo observations for 250 galaxies. We use the full GASS sample to investigate environmental effects on the cold gas content of massive galaxies at fixed stellar mass. The environment is characterized in terms of dark matter halo mass, obtained by cross-matching our sample with the SDSS group catalog of Yang et al. Our analysis provides, for the first time, clear statistical evidence that massive galaxies located in halos with masses of 10^13-10^14 Msun have at least 0.4 dex less HI than objects in lower density environments. The process responsible for the suppression of gas in group galaxies most likely drives the observed quenching of the star formation in these systems. Our findings strongly support the importance of the group environment for galaxy evolution, and have profound implications for semi-analytic models of galaxy formation, which currently do not allow for stripping of the cold interstellar medium in galaxy groups.Comment: 36 pages, 16 figures.

Testing a Model of Patient Characteristics, Psychologic Status, and Cognitive Function as Predictors of Self-Care in Persons with Chronic Heart Failure

Objective Self-care is a key component in the management of chronic heart failure (CHF). Yet there are many barriers that interfere with a patient\u27s ability to undertake self-care. The primary aim of the study was to test a conceptual model of determinants of CHF self-care. Specifically, we hypothesized that cognitive function and depressive symptoms would predict CHF self-care. Methods Fifty consecutive patients hospitalized with CHF were assessed for self-care (Self-Care of Heart Failure Index), cognitive function (Mini Mental State Exam), and depressive symptoms (Cardiac Depression Scale) during their index hospital admission. Other factors thought to influence self-care were tested in the model: age, gender, social isolation, self-care confidence, and comorbid illnesses. Multiple regression was used to test the model and to identify significant individual determinants of self-care maintenance and management. Results The model of 7 variables explained 39% (F [7, 42] 3.80; P = .003) of the variance in self-care maintenance and 38% (F [7, 42] 3.73; P = .003) of the variance in self-care management. Only 2 variables contributed significantly to the variance in self-care maintenance: age (P \u3c .01) and moderate-to-severe comorbidity (P \u3c .05). Four variables contributed significantly to the variance in self-care management: gender (P \u3c .05), moderate-to-severe comorbidity (P \u3c .05), depression (P \u3c .05), and self-care confidence (P \u3c .01). When cognitive function was removed from the models, the model explained less of the variance in self-care maintenance (35%) (F [6, 43] 3.91; P = .003) and management (34%) (F [6, 43] 3.71; P = .005). Conclusion Although cognitive function added to the model in predicting both self-care maintenance and management, it was not a significant predictor of CHF self-care compared with other modifiable and nonmodifiable factors. Depression explained only self-care management

Lineage and fate of each blastomere of the eight-cell sea urchin embryo

A fluoresceinated lineage tracer was injected into individual blastomeres of eight-cell sea urchin (Strongylocentrotus purpuratus) embryos, and the location of the progeny of each blastomere was determined in the fully developed pluteus. Each blastomere gives rise to a unique portion of the advanced embryo. We confirm many of the classical assignments of cell fate along the animal-vegetal axis of the cleavage-stage embryo, and demonstrate that one blastomere of the animal quartet at the eight-cell stage lies nearest the future oral pole and the opposite one nearest the future aboral pole of the embryo. Clones of cells deriving from ectodermal founder cells always remain contiguous, while clones of cells descendant from the vegetal plate (i.e., gut, secondary mesenchyme) do not. The locations of ectodermal clones contributed by specific blastomeres require that the larval plane of bilateral symmetry lie approximately equidistant (i.e., at a 45 degree angle) from each of the first two cleavage planes. These results underscore the conclusion that many of the early spatial patterns of differential gene expression observed at the molecular level are specified in a clonal manner early in embryonic sea urchin development, and are each confined to cell lineages established during cleavage

Pre- and postnatal development of GABA receptors in Macaca monkey visual cortex

GABA is a putative inhibitory neurotransmitter in adult mammalian visual cortex but also has been implicated as playing a crucial role in cortical information processing during development. In order to understand better the role of GABA during primate visual cortex development, we have examined the time course of GABAA and GABAB receptor ontogenesis in 18 Macaca nemestrina monkeys ranging from fetal day 61 (F61d) to adulthood. The GABA and benzodiazepine binding sites of the GABAA receptor were detected by 3H-muscimol (3H-MS) and 3H- flunitrazepam (3H-FZ), respectively. GABAB receptors were detected by 3H-baclofen (3H-BA). All ligands were visualized by in vitro autoradiography. Quantitative analysis of film density was done to compare laminar changes during pre- and postnatal development. Saturation binding experiments were done for MS and FZ binding sites to determine receptor number (Bmax) and affinity (Kd) at selected pre- and postnatal ages. Both MS and FZ binding sites were present at F61d-72d throughout the cortical plate and marginal zone. FZ binding sites were more dense than MS binding sites over the cortical plate at young ages and were especially dense over the marginal zone. FZ binding sites also were present in lesser amounts over the subplate and intermediate zone, but not over the subventricular zone. By F119d-126d, layer 4 could be distinguished by its higher density for both ligands. The basic adult laminar pattern was established for both MS and BZ binding sites by birth (birth = F165d-170d). After birth, MS density increases dramatically in all layers, but layer 4C remains most dense to adulthood. FZ labeling is heavy in both layers 4 and 3 at birth but after 4 weeks after birth (P4 wk) it declines somewhat in the supragranular layers so that layer 4C now predominates. Labeling in layers 5/6 virtually disappears after birth. BA binding sites were present at F126d, at which time layer 4 was slightly lighter than the remainder of striate cortex; this laminar pattern remained basically the same throughout our series to adulthood. Competitive binding of agonist and antagonists for the GABAA receptor showed that MS binding characteristics were similar at F126d and P8.5 years (yr). MS binding site Bmax was about 8% of adult values at F72d, 24% by F126d, and 56% at F152d. Bmax then rose rapidly after birth to peak at P18wk at 169% of adult values, and then declined to P1yr. A second peak of 143% was found around P3.5yr, with adult values reached by P8.5yr.(ABSTRACT TRUNCATED AT 400 WORDS
