“Missing Milestones”

Missing milestones are known to be a normal variant of development. The purpose of our study is to find if missing milestones always lead to normal development?

METHODS

This is a prospective case study on seven patients referred for motor developmental problems from July 1997 to February 1998 and then followed over a 2-year period. On each attendance, the multi-disciplinary team assessed children

RESULTS

We present a case series of seven children with “missing motor milestones”. Six of the seven, had tactile defensiveness but absent parachute reflexes on presentation

At the end of the two year period, 3 infants had normal development (Group I). One was discharged after 7 months. The second one had speech problems most likely secondary to her bilateral serous otitis media, with no other developmental problems. The third child acquired age appropriate milestones before the care was transferred to another hospital. Of the four in Group II, three developed global developmental delay and the fourth was diagnosed to have multiple cavernous haemangiomata in the brain. The pre-school alert panel was alerted for two of them possibly needing future help in school

Five of the seven children in our study were still being followed up after two years

CONCLUSIONS

Missing milestones in a subject can be a benign variation of normal motor development. However, they may also be the first sign to appear in children with neuro-developmental disorders

Tactile defensiveness may be the most useful early sign to enable the early diagnosis of non-weight bearing children with 'missing milestones'     

Quality children's television: the case of “Lift Off”

“Lift off” is a new, innovative children's television series produced by the Australian Children's Television Foundation. It has been well received by critics, parents, educators and most significantly, by its three-to-eight year old target audience.

The program easily satisfies the five criteria for quality programming formulated by the Children's Program Committee of the Australian Broadcasting Tribunal. The typical half-hour program is dense, requiring close viewer attention but it is claimed that the viewer is rewarded for her viewing investment with an enriching and pleasurable experience. The doubt is raised that the socially disadvantaged segment of the child audience, who use television for diversion rather than enrichment, may not be prepared to make such an investment of viewing attention.

One final concern is voiced. The Foundation's official spokespeople publicly claim that “Lift Off” will enrich the lives of a whole age cohort. It is argued that such claims overemphasise the supposed direct consequences and impact of media messages on individuals.     

“We're Very Careful …”: The Fertility Desires and Contraceptive Behaviors of Cohabiting Couples

A growing proportion of nonmarital births are to cohabiting couples, though childbearing is more common among moderately educated cohabitors than among cohabiting college graduates. In this study reasons for social class divergence in fertility behavior are explored. Data are from semistructured interviews with 30 working‐class and 31 middle‐class cohabiting couples. The authors inquired about readiness for parenthood, contraceptive usage, and concurrence about childbearing plans and contraception. Middle‐class couples generally utilized the most effective methods, often relied on two methods, concurred regarding fertility goals, and reported contracepting consistently. Among the moderately educated, contraceptive utilization was lower and reliance on less effective methods greater; they expressed greater ambivalence about preventing conception and discussed contraception less than their middle‐class counterparts. Less educated respondents also mentioned forgetfulness and cost as reasons for sporadic contraceptive use. The study results highlight the need to deepen understanding of how relational processes and couple dynamics contribute to pregnancy avoidance or conception.     

Social capital: an investment of “self” in children's learning

The concept, Social Capital, is devoting oneself affectively through implementing the CDA teaching behaviors so as to assure that children learn, like learning, and know how to learn. Since SC was previously verified as embodying five elements, the concept was investigated, using the “Preschool Teachers' Social Capital Questionnaire.” The subjects were 168 ECE teachers in both N.Y. [70] and D.C. [98], and their data were computed for appropriate measures of central tendency, variability, and relationships. The findings were: [1] subjects reported being trained in SC in their degree programs; [2] the five dimensions of SC were related to each other for teaching behaviors; [3] all SC dimensions except persistence#sh continuity over time related significantly to each other on all variables when examined separately; [4] persistence#shcontinuity over time was the one SC dimension that was positive but not significantly related to the others on training and investment of effort. Conclusion: The positive relationships support that teachers should be trained in SC and that SC should be used in teaching young children, although more study is recommended with a larger sample after the two aspects of persistence#shcontinuity over time are separated.     

“Abstinence” and “nonabstinence” models for the treatment of bulimia

One of the most controversial dimensions along which developing therapeutic approaches for bulimia can be differentiated is their allegiance to an “abstinence” or “nonabstinence” model. Through analogy to traditional treatment programs for chemical dependency, many self-help and professional programs for bulimia hold that the complete elimination of binge-vomiting behavior is a prerequisite for therapeutic work, and require abstinence from the inception of treatment. In contrast, the nonabstinence model suggests that a more gradual reduction in the frequency of episodes may be preferable in that it provides more opportunities for relapse prevention training and avoids reinforcing dichotomous thinking styles. The present paper reviews the theoretical and clinical arguments that have been advanced by each side, including the case for classifying bulimia as a substance abuse disorder. A strategy for investigating the relative efficacy of the two approaches is proposed. It is suggested that particular attention be paid to such variables as differential attrition, the effect of each modality on the accuracy of self-report, the need for continuing or supplementary therapy, the occurrence of treatment “casualties,” interactions between client characteristics and mode of therapy, and long-term results. In the interim before such data are available, a reasonable clinical recommendation may be the implementation of a “compromise” approach designed to maximize the advantages claimed by each model while minimizing possible risks.     

The Feasibility of the “Omega Kid” Study Protocol: A Double-Blind,Randomised, Placebo-Controlled Trial Investigating the Effect of Omega-3 Supplementation on Self-Regulation in Preschool-Aged Children

Self-regulation, the regulation of behaviour in early childhood, impacts children’s success at school and is a predictor of health, wealth, and criminal outcomes in adulthood. Self-regulation may be optimised by dietary supplementation of omega-3 long-chain polyunsaturated fatty acids (n-3 LCPUFAs). The aim of the “Omega Kid” study is to investigate the feasibility of a protocol to investigate whether n-3 LCPUFA supplementation enhances self-regulation in preschool-aged children. The protocol assessed involved a double-blind, randomised, placebo-controlled trial of 12 weeks duration, with an intervention of 1.6 g of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) per day (0.3 g EPA and 1.3 g DHA) in a microencapsulated powder compared to placebo. Children (n = 78; 40 boys and 38 girls) aged 3–5 years old were recruited and randomly allocated to the treatment (n = 39) or placebo group (n = 39). The HS–Omega-3 Index^® served as a manipulation check on the delivery of either active (n-3 LCPUFAs) or placebo powders. Fifty-eight children (76%) completed the intervention (28–30 per group). Compliance to the study protocol was high, with 92% of children providing a finger-prick blood sample at baseline and high reported-adherence to the study intervention (88%). Results indicate that the protocol is feasible and may be employed in an adequately powered clinical trial to test the hypothesis that n-3 LCPUFA supplementation will improve the self-regulation of preschool-aged children.     

Partitioned association-linkage test: distinguishing “necessary” from “susceptibility” loci

Marker allele-disease association and linkage between a disease locus and a marker locus are two different phenomena. Linkage without evidence of association and association without evidence of linkage are possible observations. Linkage analysis uses marker loci and the phenomenon of recombination to look for disease-related loci which are presumably major contributors to disease expression (“necessary” loci). However, the phenomenon of association is more complex. One explanation for the existence of an association is that there is a “necessary” locus in linkage disequilibrium with a marker locus. Another explanation is that the marker locus itself (or a closely linked locus in linkage disequilibrium with the marker) is a “susceptibility” locus, which increases the probability of contracting the disease but is not necessary for disease expression. Although there are other possible explanations for the existence of an association, these two can lead to different results when family data from a disease showing association are analyzed for linkage between the associated marker and the disease. If the linkage disequilibrium hypothesis is correct, there will be evidence for linkage. If the susceptibility locus hypothesis is correct, there may be strong evidence against linkage. In this work, we explore a method that could indicate whether an association is due to a susceptibility locus or a necessary locus. We show that, by dividing families based on the presence or absence of the associated marker allele in a randomly chosen affected sib, calculating lod scores, and then calculating a heterogeneity statistic, we could distinguish whether linkage data came from a susceptibility locus or a necessary locus. © 1996 Wiley-Liss, Inc.     

The meaning of “physical fitness”

The understanding of the term "physical fitness" was determined for a randomly selected sample (n = 94) of a population using a self-administered mailed questionnaire. Subjects were asked to state and give a reason for their perceived level of physical fitness, to state their perceived performance level in a number of physical fitness tests (muscular strength, daily physical work capacity, fatness, level of regular physical exercise, exercise speed, and body flexibility), and to rate how well these tests measure physical fitness. The reason most frequently stated for perceived level of physical fitness was the level of habitual physical activity (43%); significantly less frequently (P less than 0.01-0.0001) cited were reasons related to health (23%), physical performance (12%), and obesity (3%). The variation in perceived level of physical fitness was best explained by the variation in imagined regular exercise and fatness (r2 = 0.66, P less than 0.0001) with no significant additional contribution from imagined performance in remaining fitness tests. The measurement of regular exercise was most favored as a test of physical fitness. These results, taken together with evidence of the physical and psychological health benefits of regular exercise, imply that the most appropriate measure of physical fitness for the average person is an assessment of the habitual physical activity level.     

“The Wall that Stops the Outside Coming In”: Exploring Infinity and Other “Difficult” Concepts with a Preschooler

At the centre of many debates about 'developmentally appropriate practice' (NAEYC & NAECS, 1991) is the issue of difficulty and challenge. In this study we examine one preschooler's (Amy) conversations with the first author in an attempt to re-think what we as educators consider difficult for this age group. The informal interviews from which the data are drawn provide a window into mathematical queries which interest or puzzle Amy at those times, as well as the ways in which she challenges the interviewer mathematically. It is evident from these task-based conversations that topics which primary teachers and caregivers might traditionally avoid, such as 'infinity' and 'negative numbers', were concepts this four-year-old's inquiry brought into view. The authors argue that we find ways to give prominence to individual children's questioning of mathematical ideas and in turn, pause to reconsider what is 'difficult' mathematics for the early years.     

“Cloud chasers” and “substitutes”: e‐cigarettes,vaping subcultures and vaper identities

The use of e‐cigarettes is increasing, a practice denoted as vaping. We explore user motives, self‐identity as vapers and involvement in vaping subcultures, drawing on sociological theory of stigma, subcultures and symbolic boundaries. Based on analyses of semi‐structured interviews with 30 Norwegian vapers, we find that there is a vaping subculture in Norway. We identify two dominant vaper identities. The first is labelled cloud chasers. These were dedicated vapers who identified with symbols and values in the subculture. Many were politically engaged in improving vaping regulation regimes and felt a sense of belonging to a vaping community. The second group is labelled substitutes. These were former daily smokers who used e‐cigarettes for smoking cessation in a more pragmatic and defensive manner, to avoid health risks, to escape the stigma of smoking and to manage nicotine addiction. In this group, self‐identity as a vaper was generally lacking. Vaping was often symbolically linked to the stigmatised smoker identity they wanted to escape, and was restricted to private contexts. The perceived symbolic meaning of e‐cigarettes varies: for some, they are a symbol of pleasure and community. For others, they connote the stigmatised status of the addicted smoker seeking an alternative to cigarettes.
