The integration of sound, resonance, and color in Lacrimosa for alto saxophone and piano by Marilyn Shrude

American composer Marilyn Shrude has written more than thirty works that feature the saxophone prominently, comprising a substantial contribution to the instrument’s literature. This document argues that in her works for saxophone and piano, Shrude’s most notable and unique compositional trait is her conception of a non-hierarchical relationship between these two instruments. The result of this compositional approach is the combination of these sounds transforming into an integrated “third sound” that generates a unique resonance and color. To illustrate this concept, Shrude’s composition Lacrimosa (2006) is used as an exemplar. This examination considers Shrude’s musical influences from Gregorian chant, Luciano Berio, Witold Lutoslawski, and Olivier Messiaen, including the use of heterophony, simultaneous harmonic fields, resonance pitches, harmonic language, controlled aleatory, and Messiaen’s third mode of limited transposition. Shrude’s signature use of compositional devices such as pedaling, dynamics, pitch tendencies, and timbral effects are also discussed. This document includes an appendix of four interviews that detail Shrude’s biography, career, musical influences, and compositional style. The interviews also examine three of Shrude’s compositions for saxophone and piano – Shadows and Dawning (1982), Renewing the Myth (1988), and Lacrimosa (2006). The inclusion of Shadows and Dawning and Renewing the Myth provides a basis for comparing her compositional traits across multiple works for saxophone and piano

Resources and the life course: Patterns through the demographic transition

In most mammals, and in the majority of traditional human societies for which data exist, status, power, or resource control correlates with lifetime reproductive success; male and female patterns differ. Because such correlations are often argued to have disappeared in human societies during the demographic transition of the nineteenth century, we analyzed wealth and lifetime reproductive success in a nineteenth-century Swedish population in four economically diverse parishes, subsuming geographic and temporal variation. Children of both sexes born to poorer parents were more likely than richer children to die or emigrate before reaching maturity. Poorer men, and women whose fathers were poorer, were less likely to marry in the parish than others, largely as a result of differential mortality and migration. Of all adults of both sexes who remained in their home parish and thus generated complete lifetime records, richer individuals had greater lifetime fertility and more children alive at age ten, than others. The age-specific fertility of richer women rises slightly sooner, and reaches a higher peak, than that of poorer women. These patterns persisted throughout the period of the sample (1824-1896). Thus, wealth appears, even during the demographic transition in an egalitarian society, to have influenced lifetime reproductive success positively.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/29881/1/0000234.pd

Increased mitochondrial DNA diversity in ancient Columbia River basin Chinook salmon Oncorhynchus tshawytscha

The Columbia River and its tributaries provide essential spawning and rearing habitat for many salmonid species, including Chinook salmon (Oncorhynchus tshawytscha). Chinook salmon were historically abundant throughout the basin and Native Americans in the region relied heavily on these fish for thousands of years. Following the arrival of Europeans in the 1800s, salmon in the basin experienced broad declines linked to overfishing, water diversion projects, habitat destruction, connectivity reduction, introgression with hatchery-origin fish, and hydropower development. Despite historical abundance, many native salmonids are now at risk of extinction. Research and management related to Chinook salmon is usually explored under what are termed “the four H’s”: habitat, harvest, hatcheries, and hydropower; here we explore a fifth H, history. Patterns of prehistoric and contemporary mitochondrial DNA variation from Chinook salmon were analyzed to characterize and compare population genetic diversity prior to recent alterations and, thus, elucidate a deeper history for this species. A total of 346 ancient and 366 contemporary samples were processed during this study. Species was determined for 130 of the ancient samples and control region haplotypes of 84 of these were sequenced. Diversity estimates from these 84 ancient Chinook salmon were compared to 379 contemporary samples. Our analysis provides the first direct measure of reduced genetic diversity for Chinook salmon from the ancient to the contemporary period, as measured both in direct loss of mitochondrial haplotypes and reductions in haplotype and nucleotide diversity. However, these losses do not appear equal across the basin, with higher losses of diversity in the mid-Columbia than in the Snake subbasin. The results are unexpected, as the two groups were predicted to share a common history as parts of the larger Columbia River Basin, and instead indicate that Chinook salmon in these subbasins may have divergent demographic histories.Ye

Interethnic Ideology, Intergroup Perceptions, and Cultural Orientation

We examined endorsement of multicultural, assimilation, and colorblind ideologies, including their relations to stereotyping and in-group bias, among community samples of Latinos and non-Latino Whites. Participants also completed measures of their orientations to Latino and non-Latino White cultures. Analyses indicated that participants endorsed multiculturalism more strongly than colorblindness and colorblindness more strongly than assimilation. Although Latinos endorsed multiculturalism more strongly than did Whites, ratings of colorblindness and assimilation did not differ. Both groups exhibited in-group bias and out-group homogeneity. However, multiculturalism was associated with lower in-group bias. Further, Latinos who more strongly endorsed multiculturalism perceived less within group variability (i.e., had stronger stereotypes), whereas the reverse was true for Whites. Finally, analyses of cultural orientation measures indicated that ethnicity is not synonymous with cultural orientation; Latinos were equally oriented to Latino and White cultures, overall, and Latino and White American orientations were unrelated

Melatonin augments hypothermic neuroprotection in a perinatal asphyxia model

Despite treatment with therapeutic hypothermia, almost 50% of infants with neonatal encephalopathy still have adverse outcomes. Additional treatments are required to maximize neuroprotection. Melatonin is a naturally occurring hormone involved in physiological processes that also has neuroprotective actions against hypoxic-ischaemic brain injury in animal models. The objective of this study was to assess neuroprotective effects of combining melatonin with therapeutic hypothermia after transient hypoxia-ischaemia in a piglet model of perinatal asphyxia using clinically relevant magnetic resonance spectroscopy biomarkers supported by immunohistochemistry. After a quantified global hypoxic-ischaemic insult, 17 newborn piglets were randomized to the following: (i) therapeutic hypothermia (33.5°C from 2 to 26 h after resuscitation, n = 8) and (ii) therapeutic hypothermia plus intravenous melatonin (5 mg/kg/h over 6 h started at 10 min after resuscitation and repeated at 24 h, n = 9). Cortical white matter and deep grey matter voxel proton and whole brain (31)P magnetic resonance spectroscopy were acquired before and during hypoxia-ischaemia, at 24 and 48 h after resuscitation. There was no difference in baseline variables, insult severity or any physiological or biochemical measure, including mean arterial blood pressure and inotrope use during the 48 h after hypoxia-ischaemia. Plasma levels of melatonin were 10 000 times higher in the hypothermia plus melatonin than hypothermia alone group. Melatonin-augmented hypothermia significantly reduced the hypoxic-ischaemic-induced increase in the area under the curve for proton magnetic resonance spectroscopy lactate/N-acetyl aspartate and lactate/total creatine ratios in the deep grey matter. Melatonin-augmented hypothermia increased levels of whole brain (31)P magnetic resonance spectroscopy nucleotide triphosphate/exchangeable phosphate pool. Correlating with improved cerebral energy metabolism, TUNEL-positive nuclei were reduced in the hypothermia plus melatonin group compared with hypothermia alone in the thalamus, internal capsule, putamen and caudate, and there was reduced cleaved caspase 3 in the thalamus. Although total numbers of microglia were not decreased in grey or white matter, expression of the prototypical cytotoxic microglial activation marker CD86 was decreased in the cortex at 48 h after hypoxia-ischaemia. The safety and improved neuroprotection with a combination of melatonin with cooling support phase II clinical trials in infants with moderate and severe neonatal encephalopathy

Development of a Symptom-Focused Model to Guide the Prescribing of Antipsychotics in Children and Adolescents: Results of the First Phase of the Safer Use of Antipsychotics in Youth (SUAY) Clinical Trial

OBJECTIVE: To develop a new approach to prescribing guidelines as part of a pragmatic trial, Safer Use of Antipsychotics in Youth (SUAY; ClinicalTrials.gov Identifier: NCT03448575), which supports prescribers in delivering high-quality mental health care to youths. METHOD: A nominal group technique was used to identify first- to nth-line treatments for target symptoms and potential diagnoses. The panel included US pediatricians, child and adolescent psychiatrists, and psychopharmacology experts. Meeting materials included information about Medicaid review programs, systematic reviews, prescribing guidelines, and a description of the pragmatic trial. Afterward, a series of 4 webinar discussions were held to achieve consensus on recommendations. RESULTS: The panel unanimously agreed that the guideline should focus on target symptoms rather than diagnoses. Guidance included recommendations for first- to nth-line treatment of target mental health symptoms, environmental factors to be addressed, possible underlying diagnoses that should first be considered and ruled out, and general considerations for pharmacological and therapeutic treatments. CONCLUSION: Prescribing guidelines are often ignored because they do not incorporate the real-world availability of first-line psychosocial treatments, comorbid conditions, and clinical complexity. Our approach addresses some of these concerns. If the approach proves successful in our ongoing pragmatic trial, Safer Use of Antipsychotics in Youth (SUAY), it may serve as a model to state Medicaid programs and health systems to support clinicians in delivering high-quality mental health care to youths.
