To meet the [African] crisis one must turn to agricultural-led growth. But, based on historical experience, an agricultural-led strategy must be framed in no less than a twenty-year horizon and must entail a combination of technological innovation, policy reform, and institutional restructuring because each, by itself, is limited.

From the policy point of view it is essential to understand the links between firm and management characteristics and the outcome of the firm's innovative endeavours, i.e. success or failure. This is achieved via firm behaviour variables, and the causal links between variables at all three levels (characteristics, behaviour, outcome) are demonstrated using interelated sub-systems of variables derived from empirical data obtained from the SAPPHO results.  相似文献

ABSTRACT

The current study aims to present the prevalence of adverse childhood experiences and examine the healthcare costs associated with primary, allied, and specialist healthcare services. The Australian Longitudinal Study on Women’s Health is a general health survey of four nationally representative age cohorts. The current study uses 20 years of survey and administrative data (1996–2015) from the cohort born 1973–1978. Overall, 41% of women indicated at least one category of childhood adversity. The most commonly reported type of childhood adversity was having a household member with a mental illness (16%), with the most commonly reported ACES category being psychological abuse (17%). Women who had experienced adversity in childhood had higher healthcare costs than women who had not experienced adversity. The healthcare costs associated with experiences of adversity in childhood fully justify a comprehensive policy and practice review.  相似文献

Children living in out-of-home care are at greater risk of poor educational outcomes compared to other children. To address their educational needs, several programs have been developed. Within a qualitative paradigm, this study explored the experiences of students about their involvement in TEACHaR (Transforming Educational Achievement for Children at Risk), a specialized education programme. Eight students (aged 13 to 18 years) from the programme participated in individual, semi-structured interviews. Responses were analysed using Interpretive Phenomenological Analysis. Participants indicated that the programme provided individualized and flexible academic support, reduced their shame and embarrassment and provided them with more than academic support. They highlighted the importance of the student–educator relationship, and the need for encouragement and motivation to pursue their educational goals. Finally, findings report on how COVID-19 impacts on student experiences of the programme. Recommendations for the development and improvement of education programs for students in out-of-home care conclude this paper.  相似文献

conclusion In detailing the evolution of the economic landscape from factory town to electronic vil-lage and in discussing how class and collective action may be analyzed in the context of the electronic village, my goal has been to provide a framework that researchers can use to develop meaningful studies of class and collective action in the electronic village.  相似文献
