A number of African countries, including Kenya, have experienced a marked rise in births among unmarried women. In Western countries, reproduction outside of marriage is assumed to be illegitimate and a social problem. One hypothesis used to explain the increasing incidence of premarital fertility in Africa is a breakdown of traditional social controls by the extended family over the sexual behavior of adolescents. A competing hypothesis suggests that unmarried women use sexual relations to achieve goals such as marriage. Among Turkana pastoralists of northwest Kenya, we find a pattern of premarital birth that fits either hypothesis only loosely. Premarital fertility among the Turkana is both widespread and culturally acceptable, with over 30 per cent of women having at least one child prior to marriage. Although women with premarital births initiate childbearing on average one year earlier than women with only marital births, women's marital status does not influence the length of the interval between first and second births. Marriage among the Turkana is not a social trigger for the onset and continuation of reproduction or a means to legitimate reproduction. Marital status of the parents simply determines the custody of a child. In a premarital birth, the father pays a set fee to the mother's family, and the custody of the child remains permanently with the mother's family. If the parents later marry, the father must purchase custody of the child by another fee at that time. Since the Turkana have experienced few effects of modernization, the existence of such a practice suggests that cultural factors must be taken into account before assessing premarital fertility in Africa as a social problem. 相似文献

Children fall under the special category of vulnerable witnesses. Children's vulnerability is the reason that we must approach obtaining the child's testimony in the criminal proceedings with special attention. It is important to take the child's testimony as soon as possible and to avoid the repetition of interrogation. The criminal proceedings law and the juvenile court law enable children interrogation through the professional person without the presence of other parties in the procedure and enable the recording of such interrogation by audio-video link which considerably diminish the secondary victimization. The professionals who obtain the testimony must be well acquainted with children's psychological development. Knowledge of psychological development is of major importance in order to make the quality arrangements for interrogation and to interrogate the child and to achieve positive social contact between the examiner and the examinee and it is also of great importance for the credibility evaluation of the child's testimony. The adequate way of children interrogation will enable the child to say the correct information and to recognize the perpetrator. The forensic interview is well elaborated and child adapted technique of interrogation. Respecting the rules of forensic interview will enable the child's testimony on court to be relevant evidence. 相似文献

Inspired by recent efforts in the United States to quantify the degree of transnational ties that immigrants possess, this article explores and analyses the prevalence and determinants of transnational family ties of immigrants in the Netherlands. Using data from a representative survey of four immigrant groups in the Netherlands, this paper also aims to fill the gap in knowledge regarding the effects of incorporation into an immigrant's host society on transnational family ties. Findings show that, while the vast majority of immigrants with relatives in the country of origin have frequent contact with these relatives, only a third of respondents contribute to the livelihood of family members in the homeland. Incorporation characteristics show distinct patterns over different types of involvement. While incorporation variables have a negative effect on the frequency of contact, they show little effect on remittances. 相似文献

This paper investigates the possibility that birth order affects the degree to which individuals attain higher status. Humans give birth to a variable number of (usually) single offspring spaced one to many years apart, and continue to maintain contact with them for extended periods of time. The continued presence of older siblings, and arrival of younger ones, means that each child is reared in a different family environment. Research findings from the field of behavior genetics suggest that these differences have a significant impact on the development of individual differences between children in the same family. Although no two families are likely to be exactly the same, factors such as birth order remain constant across them, and may have similar influences. The present study examines the relationships between birth order, sibship size, and several variables thought to index future status attainment (status striving) in a random sample of Canadians. Firstborn children appear to be more status oriented than lastborns, and this effect is mediated by sibship size. While firstborn children are unaffected by the number of younger siblings they have, the status ambitions of youngest children decrease the more older siblings they have. Birth order effects on status attainment are not as strong as they are on status ambitions. 相似文献

A central thesis of this paper is that understanding the nature of child maltreatment is so complex that no one disciplinary specialty is likely to be sufficient for the task. Although life history theory is the guiding principle for our analysis, we argue that an evolutionary explanation adds precision by incorporating empirical findings originating from the fields of anthropology; clinical, developmental, and social psychology; and sociology. Although evolutionary accounts of child maltreatment have been largely limited to the role of the coefficient of relatedness, the prospective reproductive value of a child, and the residual reproductive potential of parents, a case is made for expanding this basic application. An explanatory model is presented that describes how ecological conditions as well as parental and child traits interact to influence the degree of parental investment. As shown in the model, these various “marker variables” alter parental perceptions of the benefits and costs associated with child care and promote low-investment parenting, which leads to disrupted family management practices and to a downward-spiraling, self-perpetuating system of coercive family interaction, increased parental rejection of the child, and even lower parental investment. Child maltreatment is the ultimate outcome of this downward trajectory of family relations. 相似文献

This article reviews the development of the laws and treaties regulating the use of child soldiers and the political, social, and cultural context in which these developments are grounded. Humanitarian and human rights groups have undertaken a major initiative to end the use of young combatants. These efforts are part of a larger children's human rights project designed to create a universal definition of "childhood." Casting the proposed ban on child soldiers in the language of human rights deflects attention from the enormity of the social and cultural changes involved in the proposed transnational restructuring of age categories. Treaty-making efforts reflect an emerging "politics of age" that shapes the concept of "childhood" in international law, and in which different international, regional, and local actors make use of age categories to advance particular political and ideological positions. 相似文献

Differential diagnosis in neurologic patients with spinocerebellar syndrome is complex as a result of the great degree of variability in phenotypic and genetic aspects of more than 200 nosological entities. In the past decade, genetic etiology has been discovered in part of the diseases and the term 'spinocerebellar ataxia' has become, from a neurologic point of view, a loose definition applied to a group of autosomal dominant diseases. Topical extensive literature about differential diagnoses of ataxias usually refers to genetics classification or is produced by a group of radiologists, elektrophysiologists and biologists as well as others in the field. A further problem is that the majority of studies do not take into account other acquired illnesses and diseases which may fundamentally alter the symptomology and course of a primary disease, not to mention the possibility of concomitancy in hereditary diseases. The following article was prompted by daily contact with ataxic patients and related issues raised by colleagues; its goal is to clarify problems faced by child neurologists and neurologists in clinical practice. 相似文献

I apply evolutionary perspectives and conceptual tools to analyse central issues underlying child health, with emphases on the roles of human-specific adaptations and genomic conflicts in physical growth and development. Evidence from comparative primatology, anthropology, physiology and human disorders indicates that child health risks have evolved in the context of evolutionary changes, along the human lineage, affecting the timing, growth-differentiation phenotypes and adaptive significance of prenatal stages, infancy, childhood, juvenility and adolescence. The most striking evolutionary changes in humans are earlier weaning and prolonged subsequent pre-adult stages, which have structured and potentiated maladaptations related to growth and development. Data from human genetic and epigenetic studies, and mouse models, indicate that growth, development and behaviour during pre-adult stages are mediated to a notable degree by effects from genomic conflicts and imprinted genes. The incidence of cancer, the primary cause of non-infectious childhood mortality, mirrors child growth rates from birth to adolescence, with paediatric cancer development impacted by imprinted genes that control aspects of growth. Understanding the adaptive significance of child growth and development phenotypes, in the context of human-evolutionary changes and genomic conflicts, provides novel insights into the causes of disease in childhood. 相似文献

Scientific literature exploring the value of assistance dogs to children with autism spectrum disorder (ASD) is rapidly emerging. However, there is comparably less literature reporting the effects of pet (as opposed to assistance) dogs to these children. In particular, there are no known validated scales which assess how children may alter their behaviours in the presence of the dog, to evaluate the efficacy of pet dogs to these families. Additionally, given the highly individualised nature of ASD it is likely that some children and families gain more benefits from dog ownership than others, yet no research has reported the effect of individual differences. This pilot study reports the development of a 28-item scale based on the perceived impact of a pet dog on a child with autism by parents (Lincoln Autism Pet Dog Impact Scale—LAPDIS). The scale is comprised of three mathematically derived factors: Adaptability, Social Skills and Conflict Management. We assessed how individual differences (aspects) may be associated with scores on these three factors. Family Aspects and Dog Aspects were not significantly associated with ratings on the three factors, but Child Aspects (including: contact with horses, child age, disability level and language abilities) were related to impact of the dog on all factors. Training Aspects were related to scores on Social Skills (formal training with children with ASD and dogs and attendance at PAWS workshops run by Dogs for Good). These results suggest that individual differences associated with the child and the training approach may be important considerations for a positive impact from dog ownership on families with children with ASD. Differences in family features and the dog may not be so important, but may be worthy of further investigations given the early stage of development in this field. 相似文献

The area of particular competence of the social worker in the habilitation of the congenitally malformed is in the social development of the child. It is an interest which continues throughout all stages of growth and development: (1) During the preschool and early life, the first consideration is to minimize or eliminate the disability. The social worker plays a supporting role to the doctor. (2) The middle years of growth are centred around the problems of education. The social worker plays an interpretative role with respect to family, school, and doctor. (3) For the adolescent and young adult the contact with the disabled person is more direct. The individual must face and solve his own problems and learn to become an independent adult. Throughout the entire development the doctor, social worker, and teacher are dependent each on the other. 相似文献

When parents are concerned about the development of stuttering in their child they often consult their pediatrician or family physician. Theories on the development of stuttering are briefly examined in this article, and guidelines are provided to help the physician determine if the child''s dysfluencies are within the normal range. Referral to a speech therapist should be considered when any of the following are noted: excessive repetition of the first syllable of words; tremor of the muscles of mouth or jaw, increase in pitch or loudness, or evidence of fear or emotion as the child struggles with a word; evidence that the child avoids certain words or situations; and excessive concern of parents, teachers or the dysfluent individual. Two approaches to therapy, traditional and behavioural, are described. The latter has resulted in significant gains in fluency among stutterers. 相似文献

This article draws together thoughts derived from an experienced clinical psychologist's practice, with parents of ill and premature infants in the context of a psychological service for children and parents in a paediatric and maternity teaching hospital. Parents were those referred by attendant neonatologists in intensive neonatal care who observed acute distress. Referral was usually some weeks after birth and help continued until after discharge, in some instances after the death of the infant. The particular approach adopted was that of offering parents a therapeutic contact which, allowed them talk over these thoughts and feelings for which they had little other skilled listening environment. Parents chose the opportunity of a safe, calm and confidential contact to explore deep feelings and draw on their own strengths and an understanding of their own vulnerabilities. The novel insights derived and the clinical material presented were used to develop an understanding of the issues a support service should address. Key aims are described and should be incorporated to restore and enhance personal strengths and the mother child relationship hence contributing to positive outcome in infant development. Reference is made to the importance of understanding how women achieve soothed states and restoration of empowerment when birth presents extra challenge. 相似文献

The better his understanding of some of the ways in which an organic deficit might affect normal development of the handicapped child, the more able the family physician will be to offer guidance to the family aimed at preventing the development of secondary problems. He can thus be instrumental in helping a child achieve his maximal potential.First, it is important to take into account how the parents'' emotional and intellectual responses to having a defective child may interfere markedly in normal parent-child relationship. Second, ways in which each deficit will limit a child''s exposure to stimuli must not be over-looked. Third, one must consider how a deficit may indirectly distort the normal learning patterns when parents do not make age appropriate demands. Fourth, it is important to understand how specific interference in the area of language skills may cause further developmental retardation. Fifth, one must be aware of special problems that an organically handicapped child must face in the society outside of the family. Last of all, in an older child, one must consider the need for a full scale evaluation to sort out primary and secondary factors in the picture. 相似文献

The law which, to some extent at least, reflects contemporary mores, has not kept pace with the recent scientific advances in genetics. Because of the rate of advance in the science of genetics there is a real risk that we shall know how to change the traditional nature of man before we possess the knowledge necessary to enable us to use the new knowledge for humane purposes. Clonal reproduction may produce a creature who, for the purposes of the law, especially the criminal law, which defines when a child becomes a human being in terms of "old-fashioned" motherhood, may not be a human being, so that putting him to death may not be homicide. Similarly, in vitro fertilization and development in an artificial uterus may result in the "birth" of one who, though having human attributes, may not, in law, be a human being. While cloning and in vitro fertilization may not have immediate legal implications because of the state of the art, genetic manipulation in the form of amniocentesis has very real legal implications now because it is a matter of current practice. The assumption that detection of genetic abnormality in the foetus is a beneficial development because it enables parents to have the option of terminating the pregnancy, though valid in the United Kingdom and the United States, is invalid in Canada. Abortion on demand is not part of the law in Canada and the liberalization of the abortion provisions of the Criminal Code of Canada in 1969 expressly avoided including as a criterion for therapeutic abortion the risk that the child, if born, would be likely to suffer from such physical or mental abnormalities as to be seriously handicapped. Beyond the more technical issues raised by scientific advances, however, lies the fundamental question whether a handicapped life is a life not worth living. 相似文献

The management of the retarded child in general practice is discussed. The necessity of a thorough medical and psychological assessment is stressed. The problem of the parents is described from the point of view of the emotional stages through which they pass and the defence mechanisms they commonly use. The factors involved in planning the future program for the retarded child are enumerated and depend on the degree of mental and physical handicap, the socio-economic and emotional climate of the family and the available services in the area. Since a large proportion of retarded children remain at home, a systematic follow-up program by the practising physician should be encouraged. 相似文献

Recently pediatricians have become more interested in the retarded child and his family and have come to realize that they have been ill-prepared to face the many problems that continually arise. A basic understanding of the role of parents and their aspirations, coupled with a knowledge of interviewing, techniques will enable them to face these problems with greater assurance. In addition, a knowledge of the community facilities and resources is necessary. This will entail direct contact with schools, parent groups, state hospitals for the retarded as well as state and local agencies which deal with the retarded. 相似文献

The socioeconomic gradient in child health and noncognitive skills: Evidence from the Czech Republic
We investigate the presence of a socioeconomic status (SES) gradient in children’s health and noncognitive skill development, and its evolution with child age using cohort data from the Czech Republic. We show that family SES are positively associated with better child health. These effects start to emerge at age 3 and are persistent for all subsequent ages. We find a modest strengthening of the gradient as the children grow older. Similarly, at the lowest distribution of average family income, children lag in their noncognitive skills. We find evidence that children enter school with substantial differences in noncognitive skill endowments based on family SES. This correlation persists when controlling for poor health at birth, the roles of specific and chronic health problems, housing conditions, and partner characteristics. Maternal health status explains some of the association between family income and child noncognitive skills. We account for the endogeniety of SES and non-linearities in measures. 相似文献

Background
Evidence is required as to when and where to focus resources to achieve the greatest gains for children’s language development. Key to these decisions is the understanding of individual differences in children’s language trajectories and the predictors of those differences. To determine optimal timing we must understand if and when children’s relative language abilities become fixed. To determine where to focus effort we must identify mutable factors, that is those with the potential to be changed through interventions, which are associated with significant differences in children’s language scores and rate of progress.Methods
Uniquely this study examined individual differences in language growth trajectories in a population sample of children between 4 and 7 years using the multilevel model for change. The influence of predictors, grouped with respect to their mutability and their proximity to the child (least-mutable, mutable-distal, mutable-proximal), were estimated.Results
A significant degree of variability in rate of progress between 4 and 7 years was evident, much of which was systematically associated with mutable-proximal factors, that is, those factors with evidence that they are modifiable through interventions with the child or family, such as shared book reading, TV viewing and number of books in the home. Mutable-distal factors, such as family income, family literacy and neighbourhood disadvantage, hypothesised to be modifiable through social policy, were important predictors of language abilities at 4 years.Conclusions
Potential levers for language interventions lie in the child’s home learning environment from birth to age 4. However, the role of a family’s material and cultural capital must not be ignored, nor should the potential for growth into the school years. Early Years services should acknowledge the effects of multiple, cascading and cumulative risks and seek to promote child language development through the aggregation of marginal gains in the pre-school years and beyond. 相似文献20.

Risk factors for child obesity may be influenced by family environment, including maternal depression, family structure, and parenting quality. We tested a path model in which maternal depression and single parent status are associated with parenting quality, which relates to three risk factors for child obesity: diet, leisure, and sedentary behavior. Participants included 4,601 5th‐grade children and their primary caregivers who participated in the Healthy Passages study. Results showed that associations of maternal depression and single parenthood with child BMI are mediated by parenting quality and its relation to children's leisure activity and sedentary behavior. Interventions for child obesity may be more successful if they target family environment, particularly parenting quality and its impact on children's active and sedentary behaviors. 相似文献
