The paper presents the child-raising model of the Israeli kibbutzim and describes the modal kibbutz adolescent. The relation of some of its significant constituents (multiple mothering, peer group living, institutionalization of values, and role expectations) to the course and the outcome of adolescent maturation is reviewed. The advantages and disadvantages of the extended psychosocial moratorium are considered, and it is suggested that time-limited adolescence may be a favorable factor on healthy personality growth. Kibbutz experience also seems to disprove the established concept that adolescent turmoil is a developmental necessity. It is hypothesized that the extension of the period of adolescence contributes to turmoil and that, as a result of this, healthy development may be partly endangered.Received M.D. from Vienna University, Austria. Current research interests are adolescent psychopathology and schizophrenia.Received B.S. from Western Reserve University and M.D. from Hebrew University, Hadassah Medical School. Current research interests are personality development of kibbutz children, development of children of schizophrenic parents, and other issues of early child development. 相似文献

Several years ago, a theory to interpret mixed DNA profiles was proposed that included a consideration of peak area using the method of least squares. This method of mixture interpretation has not been widely adopted because of the complexity of the associated calculations. Most reporting officers (RO) employ an experience and judgement based approach to the interpretation of mixed DNA profiles. Here we present an approach that has formalised the thinking behind this experience and judgement. This has been written into a computer program package called PENDULUM. The program uses a least squares method to estimate the pre-amplification mixture proportion for two potential contributors. It then calculates the heterozygous balance for all of the potential sets of genotypes. A list of "possible" genotypes is generated using a set of heuristic rules. External to the programme the candidate genotypes may then be used to formulate likelihood ratios (LR) that are based on alternative casework propositions. The system does not represent a black box approach; rather it has been integrated into the method currently used by the reporting officers at the Forensic Science Service (FSS). The time saved in automating routine calculations associated with mixtures analysis is significant. In addition, the computer program assists in unifying reporting processes, thereby improving the consistency of reporting. 相似文献

Childhood panhypopituitarism may be acquired or congenital. Children with panhypopituitarism can present clinically with diabetes, growth failure, decreased bone density, and morbid obesity. In the forensic setting without the proper history, it can be misdiagnosed as child abuse or neglect. We report a case of a 3-year-old black girl who was admitted to the emergency room with apnea and subsequently died. While at the emergency department, it was discovered that the child had a fractured left hip and was severely growth retarded for age. The coroner wanted to rule out child abuse and/or neglect and requested an autopsy based on the physical findings identified by hospital staff. Significant findings at autopsy included small for age (15th percentile for age), hypoplastic brain/pituitary gland/adrenal gland/thyroid gland, abnormally formed skull with an occipital protuberance, a fractured left hip with decreased bone density, and central adiposity. Subsequent to the autopsy, it was discovered that at 6 weeks of age the child suffered from group B streptococci meningitis that resulted in panhypopituitarism. The panhypopituitarism then resulted in seizure activity, diabetes insipidus, and growth retardation. The authors hope this case report and review of the literature will assist investigators, pathologists, and clinicians in making a distinction between neglect or inflicted injury of child abuse and panhypopituitarism that can present with similar signs and symptoms. 相似文献

We suggest a multi-layered system of three convergence criteria – similar to those used in the run-up to the European monetary union – that define the notion of "demonstrable progress" towards reaching the emission commitments under the Kyoto Protocol. These are the existence of an independently evaluated national emissions inventory, the level of domestic policies and measures, and the quantitative convergence of emissions towards the Kyoto target. While the first of these criteria constitutes a necessary condition for use of the Kyoto Mechanisms, the other two should determine the degree of participation allowed for any given Annex I country. 相似文献

Most criminal acts are committed in very small groups or alone, and are repeated sporadically. But that is not always the
case. Co-offending can include larger groups, cooperating sequentially or simultaneously, knowing each other or at least knowing
about one another. We may use the term “extended co-offending” to subsume varieties of crime organization, crime networks,
gangs, and criminal clusters. Extended co-offending also includes vaguely organized crime repetitions, and is a matter of
degree. Criminal cooperation can be extended in time, space, numbers of persons involved, and types of criminal action. The
extension process has a very wide span of possibilities. Drawing ideas from Max Weber and others, this paper suggests that
the natural history of criminal cooperation progresses in four stages, with steeply decreasing prevalence: (1) primordial
clusters of offenders, (2) small-scale charismatic leadership of offenders, (3) a medium-scale patrimonial system of offenders,
and (4) and an extended patrimonial system of criminal cooperation. Primordial co-offending occurs on a very local level,
with little or no hierarchy or systematic repetition. Extended criminal cooperation usually requires personal trust among
offenders, favoring patrimony over formal organization. 相似文献
