Eulogy on King Philip

In the heart of New England, on the doorstep of the Pilgrim founding fathers, William Apess delivered this eulogy honoring their greatest enemy, Metacomet of the Wampanoags, known as King Philip, who led a coalition of Native peoples that came close to destroying the whole English colonial enterprise in 1675–76. In 1836, one hundred sixty years later, Apess chose to re-examine the circumstances of King Philip’s life and death, and pronounced him equal to or even greater than Washington in love for his country, military skill, and personal honor. While redeeming the memory of Philip as a martyr for his people, Apes takes opportunity to indict white Christian Americans for the false promises, broken treaties, murders, enslavements, and other oppressions visited upon the Native inhabitants by the European invaders. “We say, therefore, let every man of color wrap himself in mourning, for the 22d of December and the 4th of July are days of mourning and not of joy.… the prayers, preaching, and examples of those pretended pious, has been the foundation of all the slavery and degradation in the American colonies, towards colored people.” Apess’ was a brave voice amid the prejudice and Indian Removal policies dominant in the United States. His Eulogy is an early cry by a Native author for equity, for recognition, for common humanity, and for reconciliation: “you and I have to rejoice that we have not to answer for our fathers’ crimes, neither shall we do right to charge them one to another.” William Apess (1798–1839) was born to Pequot parents, grew up among whites as an indentured servant before running away to join the militia in the War of 1812. He became a Methodist minister, preacher, author, and publisher, advocating for Native rights and for anti-slavery causes.

How vocal temporal parameters develop: a comparative study between humans and songbirds, two distantly related vocal learners

Abstract Human infants acquire motor patterns for speech during the first several years of their lives. Sequential vocalizations such as human speech are complex behaviors, and the ability to learn new vocalizations is limited to only a few animal species. Vocalizations are generated through the coordination of three types of organs: namely, vocal, respiratory, and articulatory organs. Moreover, sophisticated temporal respiratory control might be necessary for sequential vocalization involving human speech. However, it remains unknown how coordination develops in human infants and if this developmental process is shared with other vocal learners. To answer these questions, we analyzed temporal parameters of sequential vocalizations during the first year in human infants and compared these developmental changes to song development in the Bengalese finch, another vocal learner. In human infants, early cry was also analyzed as an innate sequential vocalization. The following three temporal parameters of sequential vocalizations were measured: note duration (ND), inter-onset interval, and inter-note interval (INI). The results showed that both human infants and Bengalese finches had longer INIs than ND in the early phase. Gradually, the INI and ND converged to a similar range throughout development. While ND increased until 6 months of age in infants, the INI decreased up to 60 days posthatching in finches. Regarding infant cry, ND and INI were within similar ranges, but the INI was more stable in length than ND. In sequential vocalizations, temporal parameters developed early with subsequent articulatory stabilization in both vocal learners. However, this developmental change was accomplished in a species-specific manner. These findings could provide important insights into our understanding of the evolution of vocal learning.

Early Crying, Sleeping, and Feeding Problems and Trajectories of Attention Problems From Childhood to Adulthood.

This study investigated if crying, sleeping or feeding problems that co-occur (multiple regulatory problems [RPs]) or are persistent predict attention problems and diagnoses of attention deficit hyperactivity disorder (ADHD) in childhood and adulthood. Participants were 342 individuals who were assessed at 5, 20, and 56months for crying, sleeping, and feeding (RPs) and at 6, 8, and 28years for ADHD diagnoses, attention problems, and attention span. Infants/toddlers with multiple/persistent RPs had an increased risk of receiving an ADHD diagnosis both in childhood and adulthood compared to those who never had RPs. Multiple/persistent RPs were further associated with a high-decreasing attention problems trajectory from childhood to adulthood. Interventions to alleviate early RPs may prevent the development of attention problems.

The impact of an educational intervention on knowledge about infant crying and abusive head trauma.

Infants follow a predictable trajectory of increased early crying. Frustration with crying is reported to be a trigger for abusive head trauma (AHT). To evaluate the impact of postpartum delivery of the educational program, the Period of PURPLE Crying (PURPLE), in a group of first-time mothers. The primary objective was to determine whether there was a change in knowledge about infant crying and shaking after exposure to PURPLE. Factors associated with change in knowledge were also examined. A total of 93 participants were recruited over a four-month period at a tertiary care hospital in Nova Scotia. Pre- and postintervention data were collected. Knowledge about infant crying increased significantly after program delivery (P=0.001). Low baseline crying knowledge was a significant predictor of increased knowledge about infant crying (P≤0.01). There was an insignificant decrease in shaking knowledge (P=0.5), which may have been the consequence of high baseline knowledge. An educational program for new parents appears to be warranted, especially with respect to improving knowledge about infant crying. This may have a positive benefit in AHT prevention. Additional studies are required to evaluate the impact of the program on other caregivers and on rates of AHT.

Getting the Word Out: Advice on Crying and Colic in Popular Parenting Magazines

The objective of this study is to determine whether advice in parenting magazines reflects current evidence-based understanding of early infant crying and colic, where (1) "colic" is the upper end of a spectrum of crying behavior reflective of normal infant development, and (2) physical abuse--in particular, shaken baby syndrome (SBS)--is a serious medical consequence of early crying. All available issues of 11 popular Canadian parenting magazines published between January 2000 and December 2004 were hand-searched and systematically reviewed. Fifty-one articles were found with information on: (1) causes of, (2) responses to, and/or (3) mention of SBS or abuse as a consequence of crying and/or colic. There were 105 specific causes suggested, but almost no agreement concerning the causes of crying and colic. Similarly, there were 231 specific responses to crying and colic mentioned, but little agreement among the suggested responses. For both crying and colic together, the consequence of abuse was mentioned only 7 times, and SBS only twice. Making the advice literature a truly helpful vehicle for parents concerning normal behavioral development and its consequences for their new infant seems to be a significant challenge. Arguably, this is an important shared responsibility of physicians, researchers, and journalists.

Age-related incidence curve of hospitalized Shaken Baby Syndrome cases: Convergent evidence for crying as a trigger to shaking

Objective To determine whether there is an age-specific incidence of hospitalized cases of Shaken Baby Syndrome (SBS) that has similar properties to the previously reported “normal crying curve,” as a form of indirect evidence that crying is an important stimulus for SBS. Design and setting The study analyzed cases of Shaken Baby Syndrome by age at hospitalization from hospital discharge data for California hospitals from October 1996 through December 2000. Patients All cases of children less than 18 months (78 weeks) of age for whom the diagnostic code for Shaken Baby Syndrome (995.55) in the International Classification of Disease, Ninth Edition, Clinical Modification was assigned. Results There were 273 hospitalizations for SBS. Like the “normal crying curve,” the curve of age-specific incidence starts at 2–3 weeks, has a clear peak, and declines to baseline by about 36 weeks of age. In contrast to the normal crying curve that peaks at 5–6 weeks, the peak of SBS hospitalizations occurs at 10–13 weeks. Conclusions The age-specific incidence curve of hospitalized SBS cases has a similar starting point and shape to the previously reported normal crying curve but the peak occurs about 4–6 weeks later. Of the likely predisposing causes, this pattern is only consistent with the properties of early crying. There are numerous explanations for the lag in the peaks between crying and SBS hospitalizations, including the possibility of repeat shakings prior to hospitalization. The importance of crying as a stimulus to SBS may provide an opportunity for preventive intervention.

Infant crying in context

Our focus has been on the role of early cry as a commanding source of information about infant pain and distress that requires interpretation by an adult caregiver. Its inherent ambiguity may offer an adaptive advantage, as resolution requires adult presence and scrutiny of other behavioral, physical, and contextual factors.

Strange Fruit: Billie Holiday, Café Society, and an Early Cry for Civil Rights

The lyrics of Strange Fruit, the controversial ballad that became Billie Holiday's signature song, describe a lynched black man hanging from a tree. Its performance sparked controversy and sometimes violence wherever Holiday went. This is the story of the song, from its genesis, to its popularizat

The early crying paradox

In contemporary Western societies, infants in the first 3 months cry more than at any other time during their life. Although this crying is believed to function to assure nutrition, protection, and mother-infant interaction thought to be essential for later attachment, it also predisposes to complaints of excessive crying ("colic"), discontinuing breast-feeding, and, in the extreme case, child abuse. A resolution of this apparent paradox is proposed based on evidence that elements of caregiving are important determinants of some aspects of early crying. It is argued that early human crying under caretaking conditions typical in Western societies is characterized by prolonged crying bouts, that it is specifically the length of crying bouts (rather than frequency or pattern) that is affected by caregiving practice, and that prolonged crying bouts are probably not characteristic with caretaking practices typical in non-Western societies and possibly in our evolutionary past. It is suggested that caregiving behaviors may recruit normal physiological functions that potentiate cry bout duration in Western caregiving contexts, but reduce it in others. Frequent, short bouts are sufficient, and probably better suited than long bouts, to promote all the positive and presumably adaptive functions claimed for infant crying. Furthermore, they may have provided a mechanism by which infants could enhance their own fitness.

Fetal surveillance in diabetic pregnancy. I. Predictive value of the nonstress test.

Ninety-nine consecutive diabetic pregnancies (101 infants) were monitored with altogether 2672 nonstress tests (NSTs) from about 30 weeks of gestation until parturition. In 96% of the women the last NST was performed within 2 days of delivery. Fifty-nine percent had normal NSTs throughout pregnancy. Only 3.7% of the 2 672 tests were classified as pathological. When performed within 2 days antepartum, a normal NST predicted the 1-min Apgar score to be greater than or equal to 7 in 92%, and at 5 and 10 min in 99%. When all NSTs ever performed were included, the predictive value improved to 100%. The baby's first cry within 1 min after birth was predicted in 96%. Furthermore, the predictive value of a normal NST regarding the absence of ominous intrapartum cardiotocographic (CTG) patterns, normal pulmonary function and normal metabolic balance, was about 80%. The perinatal mortality was 1%. The specificity was in general good (86-96%), whereas the predictive value of pathological tests and the sensitivity almost without exception were poor. It is concluded that the very low rate of pathological NSTs indicates that obstetric interventions were made soon after the occurrence of the first sign of fetal jeopardy. Only then, and with meticulous care, is it possible to obtain good results. A normal NST is an excellent predictor of a normal Apgar score at 5 and 10 min, and also very good for a normal 1-min Apgar and an early cry from the baby. The predictive value is quite acceptable concerning the intrapartum CTG and the neonatal course likewise regarding the pulmonary function and metabolic balance.(ABSTRACT TRUNCATED AT 250 WORDS)

Acoustic features of infant vocalic utterances at 3, 6, and 9 months.

Recordings were obtained of the comfort-state vocalizations of infants at 3, 6, and 9 months of age during a session of play and vocal interaction with the infant's mother and the experimenter. Acoustic analysis, primarily spectrography, was used to determine utterance durations, formant frequencies of vocalic utterances, patterns of f0 frequency change during vocalizations, variations in source excitation of the vocal tract, and general properties of the utterances. Most utterances had durations of less than 400 ms although occasional sounds lasted 2 s or more. An increase in the ranges of both the F1 and F2 frequencies was observed across both periods of age increase, but the center of the F1-F2 plot for the group vowels appeared to change very little. Phonatory characteristics were at least generally compatible with published descriptions of infant cry. The f0 frequency averaged 445 Hz for 3-month-olds, 450 Hz for 6-month-olds, and 415 Hz for 9-month-olds. As has been previously reported for infant cry, the vocalizations frequently were associated with tremor (vibrato), harmonic doubling, abrupt f0 shift, vocal fry (or roll), and noise segments. Thus, from a strictly acoustic perspective, early cry and the later vocalizations of cooing and babbling appear to be vocal performances in continuity. Implications of the acoustic analyses are discussed for phonetic development and speech acquisition.
