Within the context of the different product types and marketing strategies involved in ecommerce transactions, this paper suggested that high-value and time-varying products (HVTVP) made up the core of the market. These products are characterized by high brand recognition, high market price, price decay over time, and stable physical properties. This paper analyzed the structure of the pre-sale period of HVTVP and described the pre-sale period by dividing it into distinct functions. Based on this analysis, it discussed the characteristics of the logistics distribution network during the pre-sale period and established a decentralized bi-level programming model for the logistics distribution network of HVTVP within this period. This model was solved using an interactive fuzzy algorithm, which was tested and verified through numerical analysis.

BackgroundYoung people who have offended were, until recently, assessed using the Core ASSET Profile – a tool which determined their likelihood of reoffending based on their criminal history and practitioner scores across 12 domains. The repeated assessments provide a set of data for each individual which can be used to model how their risk of further offending varies over time. Having conducted an initial proof of concept study, this work explores the potential of extending the range of ‘risk’ and ‘protective’ factors using anonymised linked data held within the SAIL Databank. Main AimThe feasibility study is designed to establish the potential for using administrative data to develop a more sensitive assessment tool for use in the youth justice system. Specifically, the study explores the impact of being care experienced and of subsequent system contact in elevating the risk of further offending. ApproachA series of Bayesian hierarchical models will be generated which mimic the features of the Core ASSET Profile under the Scaled Approach. These include a range of time-varying and non-time varying variables matched to the individual, drawn from education, health and social services datasets as well as their court and offending records. ResultsThe anticipated findings will advance our understanding of how the likelihood of further offending varies over time for different groups, and how further system contact increases the risk. This will enable the complexity of young people’s real lives to be explored, and hence appropriate and timely interventions to be developed. ConclusionModelling under a Bayesian framework affords the opportunity to generate robust analysis based on smaller datasets. Findings have significant implications for policy and practice, particularly in the context of assessment processes across the justice system and social welfare.

Abstract This paper examines several research questions relating to equality and equity in Chinese higher education via an extended literature review, which in turn sheds light on evolving scholarly explorations into this theme. First, in the post-massification era, has the Chinese situation of equality and equity in higher education improved or deteriorated since the late 1990s? Second, what are the core issues with respect to equality and equity in Chinese higher education? Third, how have those core issues evolved or changed over time and what does the evolution indicate and entail? Methodologically, this paper uses a bibliometric analysis to detect the topical hotspots in scholarly literature and their changes over time. The study then investigates each of those topical terrains against their temporal contexts in order to gain insights into the core issues.

Early linguistic input is a powerful predictor of children’s language outcomes. We investigated two novel questions about this relationship: Does the impact of language input vary over time, and does the impact of time-varying language input on child outcomes differ for vocabulary and for syntax? Using methods from epidemiology to account for baseline and time-varying confounding, we predicted 64 children’s outcomes on standardized tests of vocabulary and syntax in kindergarten from their parents’ vocabulary and syntax input when the children were 14 and 30 months old. For vocabulary, children whose parents provided diverse input earlier as well as later in development were predicted to have the highest outcomes. For syntax, children whose parents’ input substantially increased in syntactic complexity over time were predicted to have the highest outcomes. The optimal sequence of parents’ linguistic input for supporting children’s language acquisition thus varies for vocabulary and for syntax.

While research on third language (L3) and multilingualism has recently shown remarkable growth, the fundamental question of what makes trilingualism special compared to bilingualism, and indeed monolingualism, continues to be evaded. In this contribution we consider whether there is such a thing as a true monolingual, and if there is a difference between dialects, styles, registers and languages. While linguistic and psycholinguistic studies suggest differences in the processing of a third, compared to the first or second language, neurolinguistic research has shown that generally the same areas of the brain are activated during language use in proficient multilinguals. It is concluded that while from traditional linguistic and psycholinguistic perspectives there are grounds to differentiate monolingual, bilingual and multilingual processing, a more dynamic perspective on language processing in which development over time is the core issue, leads to a questioning of the notion of languages as separate entities in the brain.
