Due to the layered structure and recycling characteristics, magnetic MnFe2O4/ZnFe-LDH was prepared by co-precipitation. In this study, we intensively explored MnFe2O4/ZnFe-LDH for water purification compared with the ZnFe-LDH. The morphological and structural characteristics of the obtained products were systematically characterized. MnFe2O4/ZnFe-LDH exhibits the maximum adsorption capacity of 94.52 mg/g for phosphate and 49.03 mg/g for Cr (VI), respectively, which is superior to that of the ZnFe-LDH, indicating that the magnetic MnFe2O4 effectively enhanced adsorption performance. Meanwhile, the mechanism of adsorption of phosphate and Cr (VI) was briefly studied, where the metal center ion in MnFe2O4/ZnFe-LDH and between layers of SO42- serves as capture sites for phosphate and Cr (VI) removal. Furthermore, the MnFe2O4/ZnFe-LDH can be used for magnetic recycled and still maintained excellent removal efficiency (70%) for phosphate and Cr (VI) after five adsorption-desorption cycles. This work could open a new vista of designing magnetic novel adsorbents in environmental remediation.

Early childhood marks a time where word learning is accompanied by rapid growth in the cognitive processes that underlie self-modulated and goal-directed behavior (i.e., executive functions). Although there is empirical evidence to support the association between executive functioning and vocabulary in childhood, inconsistent findings have been reported regarding the extent to which early executive functioning abilities predict later vocabulary outcomes and vice versa. To clarify the nature of the longitudinal relation between these two processes and to examine what, if any, claims can be made about their interdependence, a critical review of the literature was conducted. Also addressed are the conceptual and/or methodological differences that exist across studies conducted on this topic that may be contributing to some of the discrepancies reported in the longitudinal literature. Finally, this review provides practical and empirically informed future directions to serve as a resource for early childhood researchers advancing this area of study.

Nativist and empiricist approaches require foundationalism because they cannot account for the emergence of representation. Foundationalism is the assumption of an innate representational base. In turn, foundationalism places limits on the nature of learning as a constructivist process. In contrast, action-based approaches can account for the emergence of representation through (inter)action. In so doing, action-based approaches can pursue an emergent constructivism for learning and development. Despite the theoretical symmetry between nativism and empiricism with respect to foundationalism, there is an asymmetry in nativist and empiricist research programs. Nativism generally ignores constructivist complexity that non-nativist approaches assume needs to be investigated empirically. In practice, this means that the plethora of nativist looking-time studies do not provide adequate control conditions for the rich interpretations drawn from such research. Instead, it is the a priori assumptions of nativism doing the justification. Without such assumptions, the meaning of the data is unclear at best. Importantly, the problem of a priori assumptions driving rich interpretations is not specific to nativism or looking methodologies. Mindreading as a research program also engages in rich interpretations for studies that concern social-cognition from infancy through preschool. Similarly, these studies do not include the types of control conditions motivated by more constructivist thinking. To the extent that empiricist research programs incorporate constructivist thinking into research, they converge with action-based approaches. This creates a sort of methodological bridge between lean-empiricist research programs and action-based approaches. However, this bridge has limitations that we illustrate through an example concerning maternal mental-state discourse and theory of mind development. The ultimate conclusions are threefold: (a) Action-based approaches are the best theoretical framework for understanding learning and development; (b) constructivist methodology is multiply motivated; (c) there are varying degrees of methodological commensurability between empiricism and action-based approaches.

The COVID-19 pandemic has impacted so many aspects of family life in unprecedented ways. Some of these changes might necessitate a reexamining of how we can best research and support families as we move forward. In this editorial, we propose ways that we might examine families differently in research and approach families differently as a result of COVID-19.

Emotional availability (EA) is the ability to share an emotional connection within a dyad. The observational EA System includes the EA Scales and the EA Zones. The EA Scales consist of four adult dimensions (sensitivity, structuring, nonintrusiveness, nonhostility) and two child dimensions (responsiveness, involvement). Based on the EA Scales, EA Zones refer to “emotional attachment styles” and are patterned after traditional attachment categories (Ainsworth et al., 1978). Since the review on EA by Biringen et al. (2014), extensive research on EA has utilized the EA Scales or the EA Zones, especially with respect to clinical populations and applications. We address topics absent from the 2014 review, namely, utilizing the EA System for at-risk populations and in prevention and intervention studies. We consider EA research accounting for fathers or alternative caregivers and suggest using the whole EA system versus specific dimensions. We conclude with new directions in clinical applications of EA.
