This is the first study to estimate the association globally between violence in childhood on educational outcomes, addressing a significant gap in the current evidence base. Systematic reviews and meta-analyses were conducted to identify 67 and 43 studies respectively from 21 countries to estimate the relationship between different types of violence in childhood on educational outcomes including school dropout/graduation, school absence, academic achievement and other educational outcomes such as grade retention, learning outcomes and remedial classes. Findings show that all forms of violence in childhood have a significant impact on educational outcomes. Children who have experienced any form of violence in childhood have a 13% predicted probability that they will not graduate from school. Males who are bullied are nearly three times more likely to be absent from school and girls who have experienced sexual violence have a three-fold increased risk of being absent, AOR 2.912, 95% CI (0.904-4.92) and AOR 3.147, 95% CI (0.033-4.57) respectively. Violence in childhood also has a significant impact on children's academic achievement on standardized tests. This study shows how different forms of violence in childhood contribute to inequalities in education-for both boys and girls and that an increased investment in prevention is needed in order to meet the global Sustainable Development Goals of ending violence, raising learning outcomes and creating safe, non-violent and inclusive learning environments. More work is also needed to further define, monitor and measure the link between violence in childhood and educational outcomes in order to achieve the Sustainable Development Goals.

Food safety is a global public health issue, which often arises from asymmetric information between consumers and suppliers. With the development of information technology in human life, building a food traceability information sharing platform is viewed as one of the best ways to overcome the trust crisis and resolve the problem of information asymmetry in China. However, among the myriad information available from the food supply chain, there is a lack of knowledge on consumer preference. Based on the best-worst scaling approach, this paper investigated consumer preferences for vegetable, pork, and dairy product traceability information. Specifically, this paper measured the relative importance that consumers place on the traceable information. The results indicate that consumers have varying priorities for information in different cases. “Pesticide/veterinary use,” “picking/slaughtering date,” and “fertilizer/feed use” are the most preferred traceable information for Chinese consumers in the case of vegetables, while “picking/slaughtering date” and “history of illness and taking protective measures” are the most preferred information in the case of pork. In the case of dairy products, consumers prefer “processing information,” “environmental information of the origin,” and “traceable tag certification information” most. The results of this study call for the direct involvement of the Chinese government in the food safety information sharing system as following. First, given consumers’ diverse preferences, different types of traceable information should be recorded into the information sharing platform depending on food types. Second, the government could promote the step-by-step construction of such a platform based on the priority of consumers’ preferences. Third, new technology should be applied to guarantee the reliability of traceable information. Finally, local preferences in terms of the way consumers receive and understand information should be taken into consideration.
