A Cross-cohort Description of Young People’s Housing Experience in Britain over 30 Years: An Application of Sequence Analysis

Methods. Sequence Analysis supported by Event History Analysis. Key Findings. Despite only 12 years separating both cohorts, the younger 1970 cohort exhibited very different patterns of housing including a slower progression out of the parental home and into stable tenure, and an increased reliance on privately rented housing. Returns to the parental home occurred across the twenties and into the thirties in both cohorts, although occurred more frequently and were more concentrated among certain groups in the 1970 cohort compared to the 1958 cohort. Although fewer cohort members in the 1970 cohort experienced social housing, and did so at a later age, social housing was also associated with greater tenure immobility in this younger cohort. Conclusions. The housing experiences of the younger cohort became associated with more unstable tenure (privately rented housing) for the majority. Leaving the parental home was observed to be a process, as opposed to a one-off event, and several returns to the parental home were documented, more so for the 1970 cohort. These findings are not unrelated, and in the current environment of rising house prices, collapses in the (youth) labour market and rising costs of higher education, are likely to increase in prevalence across subsequent cohorts

Матричный Анализ Препятствий Инновационной Деятельности Для Управления Многоотраслевым Комплексом

This paper examines obstacles to innovation in a multisectoral complex. The purpose of this study is to assess the criticality of these obstacles given the sectoral heterogeneity in order to differentiate innovative policies. The research is based on the methods of matrix analysis and mathematical processing of statistical data. Numerous publications on the use of matrix models in strategic planning and management of economic development served as the information and theoretical basis for this study. To achieve the goal of the study, the authors introduce the concept of the matrix of sectoral heterogeneity of obstacles to innovation. The approach to the formation and use of this matrix is shown by the example of the diversified agro-industrial complex (AIC). The results of the study may be of practical interest in determining the priority management measures of innovation policyEste documento examina los obstáculos a la innovación en un complejo multisectorial. El propósito de este estudio es evaluar la importancia de estos obstáculos dada la heterogeneidad sectorial para diferenciar políticas innovadoras. La investigación se basa en los métodos de análisis matricial y procesamiento matemático de datos estadísticos. Numerosas publicaciones sobre el uso de modelos matriciales en la planificación estratégica y la gestión del desarrollo económico sirvieron de base teórica y de información para este estudio. Para lograr el objetivo del estudio, los autores introducen el concepto de matriz de heterogeneidad sectorial de obstáculos a la innovación. El enfoque de la formación y el uso de esta matriz se muestra en el ejemplo del complejo agroindustrial diversificado (AIC). Los resultados del estudio pueden ser de interés práctico para determinar las medidas de gestión prioritarias de la política de innovaciónПредмет исследования – препятствия инновационной деятельности в многоотраслевом комплексе. Цель исследования – оценка критичности этих препятствий с учетом отраслевой неоднородности для дифференциации мер инновационной политики. Исследование опирается на методы матричного анализа и математической обработки статистических данных. Информационно-теоретическая база исследования – публикации по использованию матричных моделей в задачах стратегического планирования и управления экономическим развитием. Для достижения цели исследования вводится понятие матрицы отраслевой неоднородности препятствий инновационной деятельности. Подход к формированию и использованию данной матрицы демонстрируется на таком многоотраслевом комплексе как АПК. Результаты исследования могут представлять практический интерес с позиции определения приоритетных управленческих воздействий инновационной политики

Main principles of developing exploitation models of semiconductor devices

The paper represents primary tasks, solutions of which allow to develop the exploitation modes of semiconductor devices taking into account complex and combined influence of ionizing irradiation and operation factors. The structure of the exploitation model of the semiconductor device is presented, which is based on radiation and reliability models. Furthermore, it was shown that the exploitation model should take into account complex and combine influence of various ionizing irradiation types and operation factors. The algorithm of developing the exploitation model of the semiconductor devices is proposed. The possibility of creating the radiation model of Schottky barrier diode, Schottky field-effect transistor and Gunn diode is shown based on the available experimental data. The basic exploitation model of IRLEDs based upon double AlGaAs heterostructures is represented. The practical application of the exploitation models will allow to output the electronic products with guaranteed operational properties
