Measures of multivariate skewness and kurtosis for tests of nonnormality

Measures of multivariate skewness and kurtosis are proposed that are based on the skewness and kurtosis of individual components of standardized sample vectors. Asymptotic properties and small sample critical values of tests for nonnormality based on these measures are provided. It is demonstrated that the tests have favorable power properties. Extensions to time series data are pointed out.     

The family culture of negotiation—a result of changing parent‐child relationships

Case studies of parent‐child relations in three different European regions—West Germany, East Germany and the Netherlands—offer material for the comparative analysis of the ongoing intra‐familial process of modernization and civilization in post‐war West European societies. The data are drawn from extended narrative interviews with twelve‐year‐olds and from parallel but separate semi‐structured ‘mirrored’ interviews with the same children and their parents. The results of the analysis show that family relations in general, and parent‐child relations in particular, are increasingly marked by a familial ‘culture of negotiation’. This suggests that the balance of intergenerational power relations is currently in the process of change. To a greater or lesser extent, contemporary family relations are characterized by situationally grounded processes of negotiation between parents and children.     

Cost analysis between options for the movement of freight

A mathematical model is developed for the comparison of cost by weight for the movement of freight between the Canadian Forces ‘Scheduled Road Freight Service’ and the commercial carriers. The study considers in detail the effect of inflation on the various factors which affect the cost that govern those economic consequences which differ between the two alternatives. An example is included to illustrate the methodology.     

Interspecies Extrapolation of Physiological Pharmacokinetic Parameter Distributions

Three methods (multiplicative, additive, and allometric) were developed to extrapolate physiological model parameter distributions across species, specifically from rats to humans. In the multiplicative approach, the rat model parameters are multiplied by the ratio of the mean values between humans and rats. Additive scaling of the distributions is denned by adding the difference between the average human value and the average rat value to each rat value. Finally, allometric scaling relies on established extrapolation relationships using power functions of body weight. A physiologically-based pharmacokinetic model was fitted independently to rat and human benzene disposition data. Human model parameters obtained by extrapolation and by fitting were used to predict the total bone marrow exposure to benzene and the quantity of metabolites produced in bone marrow. We found that extrapolations poorly predict the human data relative to the human model. In addition, the prediction performance depends largely on the quantity of interest. The extrapolated models underpredict bone marrow exposure to benzene relative to the human model. Yet, predictions of the quantity of metabolite produced in bone marrow are closer to the human model predictions. These results indicate that the multiplicative and allometric techniques were able to extrapolate the model parameter distributions, but also that rats do not provide a good kinetic model of benzene disposition in humans.     

The family planning law should be issued as soon as possible]

China is facing a baby boom in the next ten years. Now is a perfect time to formulate legislature on family planning (FP) to strengthen the current policy and regulations in order to slow the momentum of excessive population growth. As a result of current economic reform and implementation of the rural household responsibility system, the migrant population has increased tremendously. The fact that millions of rural farmers are shifting to non-agricultural areas created new challenges to the effectiveness of traditional measures of the FP program. Promulgating laws and legislature will facilitate the job of FP. The law should stress the restriction of population growth and encouraging one child per couple. In the rural area it is not feasible to implement the one child policy indiscriminately. Under the policy of one child for a majority of the couples, no third birth is permitted. Local governments should be given the authorization to grant permission for second births for special cases within the birth planning quota. Allowing people living in poor and less developed areas to have more children and granting mothers of handicapped children permission to have an additional child were in fact facilitating the deterioration of the quality of the population. Some current policy in rural income distribution and social welfare was beneficial to large-sized family. Such policies should be changed to give incentives to small-sized families.

Time to reconceptualize ‘green technology’ in the context of globalization and international relations

The focus on time is used to demonstrate that Newtonian conceptions of reality underpin the push for ‘green technology’ and its associated international relations. It brings to the surface the rationale of this technology and shows its limits and future potential by exploring underlying assumptions and principles: ‘green technology’, it is argued, is not achievable on those terms and such an approach to environmental problems is unlikely to lead to relevant action and suitable solutions. It is not simply a matter of finding the ‘right technical, economic and political solutions but, crucially, about reconceptualization and the restructuring of knowledge. Thus, conceptual revision is necessary if appropriate responses are to be found to the hazards of the industrial way of life; focus on the temporal dimension of technology and globalized political processes offers a first point of departure from the Newtonian tradition.     

Medical examinations for child sexual abuse in Scotland: good enough practice?

This questionnaire survey of a representative sample of practitioners in Scotland sought to establish speci?cally how widely guidance on child protection issued by the Scottish Executive Health Department was being followed by practitioners, NHS Trusts and health boards. It aimed to identify the medical practitioners involved and the range of current practice in child sexual abuse examinations throughout Scotland. The results suggest that the medical assessment of children who disclose sexual abuse is a low‐volume, highly specialized activity, practised by about one in ?ve paediatricians and forensic medical examiners in Scotland. Most (79%) are aged between 41 and 60 years; 59.8% have less than 10 years' experience in the ?eld; and the majority (86.3%) perform fewer than two examinations per week. Available guidance is comprehensive and uniform, highlighting the importance of joint specialist working, use of the colposcope for photodocumentation, training and continuing professional development in this specialized area of work. Despite this, the results of our survey of practitioners show that throughout Scotland, the care offered to children and the service provided to the courts are suboptimal.
