Parent book choices: How do parents select books to share with infants and toddlers with language impairment?

Book-sharing with young children is an established vehicle for promoting early language development and pre-literacy skills. Although parents are widely encouraged to read to their child and existing interventions provide instruction on book-sharing strategies, there is a prominent lack of guidance for parents on how to choose the book itself. Importantly, there is a foundational lack of knowledge on the factors that parents take into consideration when choosing books to share with their young child. While understanding that parent book-choice is important for all children, it may be particularly important for those with language-impairment (LI), since book-sharing is an evidence-based intervention approach and widely recommended to promote language for LI populations. This qualitative study examines parents' book selection choices, and the elements they consider, when choosing books to share with their infants and toddlers with LI. Participants included 13 parents of young children aged 19-29 months (9 males, 4 females; mean age 25 months) receiving Part C services. Parent responses indicated that the most common themes considered included physical aesthetics, text difficulty, physical properties, educational considerations and content; the relative importance of these themes varied depending on context. Results are framed in the context of research on parent-child book-sharing interactions. Recommendations for practitioners working with parents and young children with LI during book-sharing are also highlighted.

Shared Book Reading Intervention for Parents of Infants and Toddlers.

Shared book reading is a well-established vehicle for promoting child language and early development. Yet, existing shared reading interventions have primarily included only children age 3 years and older and high quality dialogic strategies have been less systematically applied for infants and toddlers. To address this gap, we have developed a book-sharing intervention for parents of 12- to 36-month-olds. The current study evaluated acceptability/usability and preliminary efficacy of book-sharing intervention in a randomized controlled trial. Parent-child dyads were randomized to either 8-week book-sharing intervention (n=15) or wait list control (n=15). Parent book-sharing skills were assessed at baseline, post-intervention, and 2-month follow-up. Results indicated parents found the intervention highly acceptable and useful. Parents receiving intervention demonstrated significant improvement in book-sharing strategies compared to controls at post-intervention and 2-month follow-up. The current study provides evidence for the benefit of a brief, low intensity, targeted intervention to enhance parent book-sharing with infants and toddlers.

The past, present and future of hormonal contraceptive use in managed captive female tiger populations with a focus on the current use of deslorelin acetate.

Tigers (Panthera tigris spp.) are endangered in the wild; ensuring sustainable insurance populations requires careful planning within zoological collections. In captive situations, contraceptives are often used to control breeding and ensure genetically viable populations that contain manageable numbers of animals; reversible contraceptives are ideal because they offer flexibility for breeding management. Historically, synthetic progestins, such as melengestrol acetate implants, were used in female tigers, but these are associated with an increased risk of reproductive pathology and subsequent infertility. Recent management advice to ex-situ collections has been to transition to the use of gonadotropin-releasing hormone agonists, such as deslorelin acetate implants, which do not appear to have a similar risk of reproductive pathology but are associated with highly variable reversal times in exotic felids. Using data from 917 contraceptive records in female tigers captured by the Association of Zoos and Aquariums Reproductive Management Center and the European Association of Zoos and Aquaria Reproductive Management Group's joint Contraception Database and from supplementary surveys, this study reviews the changing use of contraceptives in captive female tigers. The aim was to describe the historical and current use of contraceptives and provide a comprehensive assessment on the use of deslorelin implants, including data on product protocols, efficacy, pathology, and reversibility. This study determined that current dose, frequency, reversibility, and anatomical placement sites of deslorelin implants are highly variable, indicating that specific, readily available, unified, evidence-based recommendations on the use of deslorelin would be useful for future contraceptive use in managed tiger populations.
