Effective bilingual practices for early childhood reading and language arts :/ a professional development seminar and model thematic unit for English-Spanish bilingual educators

This project provides a workshop framework for the implementation of effective bilingual practices in early childhood reading and language arts. It is designed as a series of workshops for English-Spanish bilingual educators, with the purpose of providing ideas and strategies to support the development of reading and language arts programs in both languages. It is important to point out that the success of a language program relies not only on excellent research, but also on the support of parents, teachers, administrators and the whole community. It is important to believe that no language is superior to any other, that the language and literacy acquisition of more than one language provides for a more resilient cornerstone for cognition and a more diversified body of mental abilities (Izquierdo, 2000, p. 6)

The role of attitude toward chatbots and privacy concern on the relationship between attitude toward mobile advertising and behavioral intent to use chatbots.

Abstract Chatbots are technological tools equipped with artificial intelligence that allow companies to interact with their consumers. Through their computers or mobile devices, consumers can use this technology to search for information, make purchases or request after-sales services. This study aims to identify the role of attitude toward chatbots and privacy concern in the relationship between attitude toward mobile advertising and behavioral intent to use chatbots. After reviewing the literature, the study proposes a moderated mediation model. Through a survey, the study shows that attitude toward mobile advertising does not have a direct effect on the behavioral intent to use chatbot, but is rather mediated by one’s attitude toward chatbots. In fact, the interactivity is unidirectional in the case of mobile advertising (from the company to the consumer), but bidirectional in the case of chatbots (in which consumers have an active role in communication). In line with these assumptions, the data analysis shows that internet privacy concerns only negatively moderate the relationship between attitude toward chatbots and behavioral intent to use this technology. These results can be useful for companies and researchers in terms of developing and testing new digital marketing strategies. The paper concludes with a discussion of the results’ theoretical and managerial implications

A Bibliometric Review of Digital Nudging within Digital Food Choice Environments

People increasingly make choices about their food intake in digital environments (e.g., online food delivery, online grocery shopping, online school canteens). Given the critical role of diet quality as a key driver for non-communicable disease, it is vital to understand how to design such systems to facilitate healthy food choice through digital nudging. To better understand the impact of digital technologies on food choice, we need to understand the knowledge structure of previous literature. A systematic review of literature identified 83 relevant publications which have been included in this study. Bibliometric analyses were used to map out the knowledge structure, historical roots, and evolution. Reference year spectroscopy, co-word analysis and co-citation analysis were used. Findings show digital nudging is a rapid growing field with strong historical roots in psychology. Additionally, current literature is utilizing psychological theories during the development of digital technologies aimed at nudging consumers towards healthier food options

Dissociate lattice oxygen redox reactions from capacity and voltage drops of battery electrodes.

The oxygen redox (OR) activity is conventionally considered detrimental to the stability and kinetics of batteries. However, OR reactions are often confused by irreversible oxygen oxidation. Here, based on high-efficiency mapping of resonant inelastic x-ray scattering of both the transition metal and oxygen, we distinguish the lattice OR in Na0.6[Li0.2Mn0.8]O2 and compare it with Na2/3[Mg1/3Mn2/3]O2. Both systems display strong lattice OR activities but with distinct electrochemical stability. The comparison shows that the substantial capacity drop in Na0.6[Li0.2Mn0.8]O2 stems from non-lattice oxygen oxidations, and its voltage decay from an increasing Mn redox contribution upon cycling, contrasting those in Na2/3[Mg1/3Mn2/3]O2. We conclude that lattice OR is not the ringleader of the stability issue. Instead, irreversible oxygen oxidation and the changing cationic reactions lead to the capacity and voltage fade. We argue that lattice OR and other oxygen activities should/could be studied and treated separately to achieve viable OR-based electrodes

Perceived social welfare as a driver of green products consumption: Evidences from an integrated multi-trophic aquaculture production

This study investigated consumers' perceptions of green products derived from a circular economy production, by shedding light on the role of perceived social welfare. Furthermore, the paper considered two moderators: perceptual variables on green products and psychological variables on the environment. The analysis was performed in the aquaculture sector—specifically referring to Integrated Multi-Trophic Aquaculture (IMTA) production as a research setting. Respondents received a structured questionnaire containing scales that measured perceived social welfare, environmentalism, green product's perception (in terms of price, quality and usefulness), purchase intention, and word-of-mouth. The results revealed an inverse relationship between perceived social welfare and the behavioral variables. Consumers were more attracted to and focused on the green product's usefulness than its price and quality. Moreover, the study found that environmentalism (in terms of environmental concern and perceived consumer effectiveness) moderate the effect of perceived social welfare on dependent variables. By exploring the role of perceived social welfare as a regressor, this study improves our understanding of consumers' behavior toward green products

Short- and Longer-Term Benefits of Temporary Alcohol Abstinence During ‘Dry January’ Are Not Also Observed Among Adult Drinkers in the General Population: Prospective Cohort Study

Aims The alcohol abstinence challenge ‘Dry January’ continues to grow, but there is a lack of knowledge of how Dry January participants compare to the general population. There is also a need to determine whether benefits experienced by Dry January participants are unique to that group or are also observed among other people. Methods We conducted a prospective cohort study using online questionnaires in early January, February and August 2019. We compared 1192 Dry January participants and 1549 adult drinkers who did not attempt to abstain from alcohol. Key outcomes were self-rated physical health, psychological well-being (Warwick–Edinburgh Mental Well-Being Scale), control over drinking (Drink Refusal Self-Efficacy Scale (DRSE)) and alcohol intake (Alcohol Use Disorders Identification Test–Consumption (AUDIT-C) subscale). Baseline differences in demographic and alcohol consumption variables were included as covariates in between-group analyses. Results Dry January participants had higher SES, poorer well-being, higher AUDIT-C scores and less control over their drinking than the general population. Beneficial changes in health, WEMWBS, DRSE and AUDIT-C observed among people completing Dry January were not observed among other adult drinkers. Conclusions Dry January appears to attract people who are heavier drinkers than the general population and who are more concerned about their alcohol intake. Completion of Dry January is associated with short- and longer-term benefits to well-being that are not observed in the general population

High Reversibility of Lattice Oxygen Redox in Na-ion and Li-ion Batteries Quantified by Direct Bulk Probes of both Anionic and Cationic Redox Reactions

The reversibility and cyclability of anionic redox in battery electrodes hold the key to its practical employments. Here, through mapping of resonant inelastic X-ray scattering (mRIXS), we have independently quantified the evolving redox states of both cations and anions in Na2/3Mg1/3Mn2/3O2. The bulk-Mn redox emerges from initial discharge and is quantified by inverse-partial fluorescence yield (iPFY) from Mn-L mRIXS. Bulk and surface Mn activities likely lead to the voltage fade. O-K super-partial fluorescence yield (sPFY) analysis of mRIXS shows 79% lattice oxygen-redox reversibility during initial cycle, with 87% capacity sustained after 100 cycles. In Li1.17Ni0.21Co0.08Mn0.54O2, lattice-oxygen redox is 76% initial-cycle reversible but with only 44% capacity retention after 500 cycles. These results unambiguously show the high reversibility of lattice-oxygen redox in both Li-ion and Na-ion systems. The contrast between Na2/3Mg1/3Mn2/3O2 and Li1.17Ni0.21Co0.08Mn0.54O2 systems suggests the importance of distinguishing lattice-oxygen redox from other oxygen activities for clarifying its intrinsic properties.Comment: 33 pages, 8 Figures.
