Solidarity, children and research

While research on children is supported by many professional guidelines, international declarations and domestic legislation, when it is undertaken on children with no possibility of direct benefit it rests on shaky moral foundations. A number of authors have suggested that research enrolment is in the child's best interests, or that they have a moral duty or societal obligation to participate. However, these arguments are unpersuasive. Rather, I will propose in this paper that research participation by children seems most reasonable when considered as an act of solidarity; a form of identification with, and provision of practical assistance to, those who are less well off. This is an articulation of the view that many children, and their parents, seem to take seriously the suffering of others, and wish to assist in advancing other children's wellbeing. Perhaps, by fostering an environment in which children are encouraged to take solidarity seriously, participation in research which holds out substantial hope of benefit to those less well off would come to be perceived as a behavioural norm rather than an exceptional practice.     

Bioethics,children, and the environment

Queer perspectives have typically emerged from sexual minorities as a way of repudiating flawed views of sexuality, mischaracterized relationships, and objectionable social treatment of people with atypical sexuality or gender expression. In this vein, one commentator offers a queer critique of the conceptualization of children in regard to their value for people's identities and relationships. According to this account, children are morally problematic given the values that make them desirable, their displacement of other beings and things entitled to moral protection, not to mention the damaging environmental effects that follow in the wake of population growth. Objectionable views of children are said even to have colonized the view of lesbian, gay, bisexual, and trans (LGBT) people who – with the enthusiastic endorsement of bioethics – increasingly turn to assisted reproductive treatments to have children. In the face of these outcomes, it is better – according to this account – that people reconsider their interest in children. This account is not, however, ultimately strong enough to override people's interest in having children, relative to the benefits they confer and relative to the benefits conferred on children themselves. It is certainly not strong enough to justify differential treatment of LGBT people in matters of assisted reproductive treatments. Environmental threats in the wake of population growth might be managed in ways other than devaluing children as such. Moreover, this account ultimately damages the interests of LGBT people in matters of access, equity, and children, which outcome is paradoxical, given the origins of queer perspectives as efforts to assert and defend the social interests of sexual and gender minorities.     

Multiple classification performance of juvenile chimpanzees,normal children,and retarded children

The cognitive capacities of juvenile chimpanzees, normal children, and retarded children were evaluated by using a nonverbal, Piagetian-type multiple classification task. The three groups of subjects were tested with the same two by two stimulus matrix, which was formed by combining two different colors with two different shapes. On each problem the subjects were required to select one of four stimulus items from the response tray and place it inside the empty cell of the stimulus matrix. It was found that the human and nonhuman primates tested were able to select objects with correct color and shape cues (C⁺/S⁺)significantly more often than the other objects with only color cues correct (C⁺/S^-), only shape cues correct (C^-/S⁺), or neither cue correct (C^-/S^-). Although the two groups of human children were able to select the C⁺/S⁺ objects about 100% of the time by the end of testing, the normal children required significantly fewer problems than the retarded children. The juvenile chimpanzees needed significantly more problems than the human subjects before they consistently selected the C⁺/S⁺ object on the first trial and attained a level of correct responding that was above chance. Moreover, their level of performance did not exceed 70% correct. These data suggest that the human children (both normal and retarded) used a conceptual strategy, while the juvenile chimpanzees employed a perceptual strategy to solve the multiple classification problems. The relationship between language and conceptual problem-solving strategies for Piagetiantype tasks is discussed. Portions of the data reported in this study were presented at the Annual Meeting of the Southern Psychological Association, Atlanta, Georgia, March 15–18, 1978.     

Socioeconomic status, height, and obesity in children

The substantial increase in the prevalence of child obesity over recent decades and its association with a number of negative health and economic outcomes suggests its strong potential as an influence on the lifecourse development of health and productivity. This paper evaluates interactive effects between family socioeconomic status (SES) and height on child obesity in the United States. Using the 1999-2006 National Health and Nutrition Examination Surveys (NHANES), the results of this paper confirm previous findings that taller children exhibit greater propensity towards obesity as measured by body mass index (BMI) and that obesity is inversely related to family SES as measured by poverty status. The analysis adds to the existing literature by showing that the magnitude of the SES-obesity association is larger in taller children. Age and sex patterns are evaluated that suggest the SES-height interaction persists through childhood and adolescence in males but is only evident in females during adolescence. Interaction effects are also shown to be most evident in white males and Hispanic females. Policy implications are discussed and directions for future work are suggested.     

Moles,melanomas and epitheliomas in children

The management of moles which occur in childhood is important from the standpoint of clinical diagnosis and treatment. Melanomas of both the malignant and juvenile types are sometimes mistaken for ordinary moles. Malignant epithelial tumors are rare in childhood as are congenital tumors. There is a possible relationship between congenital defects of various types and childhood neoplasms.     

Height, weight, and blood pressures in ten-year-old children

Multiple regression techniques were used to determine the most efficient combination of height, weight and body mass index in the prediction of systolic and diastolic blood pressures for a national sample of 13,723 10-year-old children. In every analysis an adjustment was made for the depth of sphygomomanometer cuff used when taking the blood pressure. The variables which together best predicted the systolic blood pressures in boys were weight, height and (height)2, and in girls weight/(height)2 and height. Diastolic blood pressures were predicted best by weight only for boys and by weight/(height)2 and height for girls. Once these factors had been taken into account there was no difference in blood pressures in those children for whom there were signs of puberty.     

Asthma episodes: stigma, children, and Hollywood films

Asthma has been systematically stigmatized in Hollywood feature films, including films seen by children. Through content analysis of 66 movies containing one or more scenes showing asthma, and through informant interviews with a dozen U.S. children about representative scenes, the study explores how stigmatizing portrayals are interpreted, accepted, or resisted. Children suffering from asthma actively counterargued with incriminating excerpts, but in some respects their healthy friends were less critical. Overall, children viewed stigmatizing scenes in terms of the social interaction and the social ethics entailed. They did not scrutinize the characters for damaged selfhood, per se, but dwelled on the social processes out of which stigma is erected.     

Cerebrospinal fluid,plasma, and urinary MHPG in children

Cerebrospinal fluid (CSF) free MHPG levels for six autistic and four medicated Tourette Syndrome (TS) patients are in the usual adult range, but levels are elevated in two recently medicated TS patients. Plasma free MHPG levels in unmedicated autistic and TS patients are similar to those in normal boys, but are increased in two of seven medicated TS patients. There is a strong association between plasma free MHPG and urinary total MHPG levels in normal boys. Age and total urinary MHPG are positively correlated in autistic children. MHPG appears to be a useful index of noradrenergic function in childhood neuropsychiatric disorders.     

Stride length and speed for adults, children, and fossil hominids

Research workers studying the relationship between stride length (L) and speed (u) in human walking have often expressed their results as multiples of stature (h): they have given values of L/h and u/h. They have claimed or implied that this takes account of differences of body size and that L/h should be the same function of u/h for people of all sizes. It is shown that this is not true for comparisons of children with adults. Further, it is argued by dimensional analysis that u/square root gh is a more appropriate speed parameter that u/h (g is the acceleration of free fall). It is shown that L/h is approximately the same function of u/square root gh for children aged 4 or more years as for adults. The empirical relationship between L/h and u/square root gh is used to make new estimates of walking speed for the early hominid footprints found at Laetoli, Tanzania. The speeds obtained are equivalent to mean speeds of human walking observed in small towns (i.e., they give approximately equal values of u/square root gh).     

Trauma, dreaming, and psychological distress among Kurdish children.

The authors examined (a) how traumatic events are associated with children's dream structure and content and (b) which dream characteristics might moderate the negative impact of traumatic events on mental health. Participants were 122 Kurdish children (9-17 years old, M = 13.02, SD = 1.66). Their dreams were collected during 1 week using a semistructured dream diary and scored according to the dream atmosphere, the role of the dreamer, bizarreness, narrative quality, fragmentation and resolution, and content such as themes of death, persecution and rejection, hostility, and anxiety. The results substantiated the hypothesis that children exposed to a high level of traumatic events would report dreams characterized by unpleasant atmosphere, fragmented flow, and low levels of bizarre narrative quality. Pleasant dreams containing complete narratives and happy endings moderated the negative impact of traumatic events on children's mental health. The authors argue that dreaming allows cognitive-emotional processing of traumatic events and may thus enhance child well-being in war conditions.

Immunity of children to diphtheria,tetanus, and poliomyelitis.

A survey of titres of diphtheria and tetanus antitoxins and of antibodies to polioviruses in the sera of 291 schoolchildren aged 15, 11, and 7 years showed that high immunisation rates can evoke protective concentrations of tetanus antitoxin in 98% of children and protective levels of the antibodies to diphtheria and all three types of poliomyelitis in 85% of children. Reinforcing immunisation at school entry appeared to be necessary to maintain adequate titres of diphtheria antitoxin in children up to 15 years of age, not essential to maintain adequate titres of tetanus antitoxin, and to have little effect on the titres of antibodies to poliomyelitis.     

Intestinal microflora in children from Mongolia, Russia, and Switzerland

Intestinal microflora was studied in 3 groups of children; 55--living in Mongolia, 18--in Switzerland and 28--in Russia. Age of children of both sexual groups was 1.5-3 years. This study revealed that in none of these groups of clinically healthy children living in different regions and having different diet normal intestinal microflora corresponded to the standard considered to be the norm. The revision of norm criteria for normal intestinal microflora in children is recommended.     

Immunoreactive urinary prostaglandins A and E in neonates, children, and adults

Urinary prostaglandins were measured by radioimmunoassay in neonates (31–35 weeks gestational age), children (4–15 years) and adults (24–36 years). Neonates showed significantly lower levels of both iPGE and iPGA compared to children (p<0.01) and adults (p<0.01). Children also had significantly lower levels than adults (p<0.01). Since urinary prostaglandins reflect intrarenal levels of prostaglandins, the results support other studies that suggest prostaglandins may play a role in controlling renal blood flow in infants.
