MATHEMATICAL MODELS AND RECOGNITION METHODS FOR MOBILE SUBSCRIBERS MUTUAL PLACEMENT

The challenge of mobile subscribers’ groups and crowd’s behavior prediction during the mass events is now increasingly important. Operative methods application of this task solution is difficult; accordingly, development and application of technical methods is necessary. The method of this problem solution consists of subscribers’ telephone conversations recording in a zone of mass action, and the following speech recognition, the semantic analysis and statistical processing application. However, there is a tendency demand decrease for mobile systems voice services with simultaneous demand growth for data traffic nowadays. The purpose of this paper is to create a mathematical model of mobile networks subscribers’ mutual placement types, applicable for automatization of the subscribers’ activities nature prediction systems. The research method consists of mathematical simulation model development for pseudo-random examples generation of subscribers’ mutual placement types set, creation of training dataset, convolution neural network training and usage of training results to recognize the new examples. The results obtained. A mathematical model is proposed allowing to create a representative training and validation dataset of mobile networks subscribers’ mutual placement types for neural network training and testing. The convolution neural network trained using these samples has shown high classification accuracy results with a wide class of subscribers’ mutual placement types.

A Four-Nation Comparison of Kinship Care in the UK: The Relationship between Formal Kinship Care and Deprivation

The practice of extended family and friends helping to care for children when their parents are unable to is an enduring tradition in many cultures. Kinship care provides the largest proportion of out of home care in Western society but many of these carers experience poverty and deprivation, and do not receive comparable levels of support, financial or professional, to other placement types. This study provides UK evidence for the relationship between kinship care and deprivation and examines how the welfare state frames kinship care in policy and practice.

How to Mix Brand Placements in Television Programmes to Maximise Effectiveness

This research, based on 20 brand placement campaigns for 17 brands in 11 Belgian entertainment shows, uses the mixture modelling technique to identify the optimal mix of brand placement types in a programme. It determines the ideal proportions of prop placements (branded products that are put on display during the programme, without active interaction between the product and a person), interactive placements (placements that entail interaction between a branded product and a person), and look-and-feel placements (branding elements that are visually incorporated in the scenery of the programme) to maximise brand attitude and brand recall. Controlling for programme connectedness, brand attitude is maximised when all brand placements in a programme are interactive. The optimal mix for brand recall is more diverse, and changes for consumers with different viewing frequencies. For light viewers, 39% interactive and 61% prop placements should be used. For consumers with high viewing frequency, a relatively larger proportion should be allocated to interactive placements (44%).

Permanency and Safety Among Children in Foster Family and Kinship Care: A Scoping Review

Over the past 25 years, kinship care placements have risen dramatically, such that when a child enters into care, child welfare agencies must first attempt to identify safe living arrangements with relatives or individuals known to the child before searching for alternatives. Despite the growing emphasis on kinship care, little is known about its impact on child outcomes in comparison to other placement types (e.g., foster family). Therefore, the aim of this scoping review was to evaluate quantitative research on children in out-of-home care from 2007 to 2014 with regard to the following outcomes: (1) permanency (i.e., reunification, reentry, placement stability, and adoption/guardianship) and (2) safety (e.g., additional reports to child welfare). Based on these objectives, the review identified 54 studies that examined permanency and safety among children in two major placement types, namely foster family and kinship care. Across studies, children in kinship care experienced greater permanency in terms of a lower rate of reentry, greater placement stability, and more guardianship placements in comparison to children living with foster families. Children in kinship care, however, had lower rates of adoption and reunification. The findings also indicated that differences in these variables diminish over time. Findings for safety outcomes were mixed. Study methodological limitations and recommendations for future research are considered.

Child Welfare-Involved Youth With Intellectual Disabilities: Pathways Into and Placements in Foster Care

Existing literature suggests that youth with intellectual disabilities are at increased risk for child maltreatment. Little is known about youth with intellectual disabilities who are supervised by child welfare authorities or living in foster care. Reasons for child welfare system involvement and placement types are explored. In this cross-sectional exploratory study, we drew on data from the Adoption and Foster Care Reporting System (AFCARS) for youth in 46 states, the District of Columbia, and Puerto Rico. A sample of 17,714 youth with intellectual disabilities and a comparison group (n = 655,536) were identified for 1999. Findings have implications for preventing the removal of youth from caregivers and the promotion of community inclusion of foster youth while in foster care.
