Developing a comprehensive model of risk and protective factors that can predict spelling at age seven: findings from a community sample of Victorian children

The paper reports on a study designed to develop a risk model that can best predict single-word spelling in seven-year-old children when they were aged 4 and 5. Test measures, personal characteristics and environmental influences were all considered as variables from a community sample of 971 children. Strong concurrent correlations were found between single-word spelling and single-word reading while expressive language and, to a lesser extent, receptive language were less strongly correlated. Predictors of single-word spelling at ages 4 and 5 were dominated by child-related factors such as letter knowledge, a history of speech impairment and expressive language along with maternal word reading ability. Based on the strength of the predictive factors identified at both age 4 and 5, our results provide initial support for using a targeted model for screening pre-schoolers at risk of not mastering spelling in a timely manner.     

The Challenges of Teaching the Introductory LIS Management Course

Teaching the introductory LIS management course may be the most challenging assignment for LIS professors because of the breadth of the subject, the probabilistic nature of management principles, and the differing management environments of LIS organizations. The best teaching strategy is to describe honestly to students the benefits and limitations of the course and to focus on the achievable objectives of introducing students to core management concepts, providing skill enhancement, and encouraging them to evaluate their management potential. The article discusses the difficulties of teaching leadership skills, the limits imposed by student competencies, and the impact of the professor's background on course content.     

The use of economic classifiers for the indexing of scientific publications

The experience from the application of the OKVED 2 economic classifier for indexing scientific publications is considered. More than 9500 articles on the subject of “Automation. Computer Engineering” in authoritative Russian magazines were the material for the study. Some means for the comparative analysis of economic statistics and results of the classification of scientific publications are shown.     

Adolescents and Movie Ratings: Is Psychological Reactance a Theoretical Explanation for the Forbidden Fruit Effect?

Adolescents were recruited to participate in an experiment to assess whether psychological reactance can provide a theoretical explanation for the forbidden fruit effect in the context of movie rating restrictions. In addition to examining if movie ratings served as antecedents to freedom threat perceptions, we investigated the role authoritarian parents had on freedom threat perception and reactance arousal. Results indicated that a movie with an NC-17 rating was perceived as a stronger freedom threat than R and PG-13 rated movies. Interestingly, adolescents who perceived their parents to be authoritarian were less likely to view movie ratings as a freedom threat. As expected, freedom threat perceptions were positively associated with psychological reactance. Reactance, in turn, was positively associated with both first and third person attitudes. The results are discussed with an emphasis on the theoretical and practical implications of the findings.     

Gay On-Screen: The Relationship Between Exposure to Gay Characters on Television and Heterosexual Audiences' Endorsement of Gay Equality

The current study, grounded in the parasocial contact hypothesis, employed a survey of emerging adults to investigate the relationship between exposure to gay characters on television and heterosexuals' endorsement of gay equality. A positive relationship existed between exposure to on-screen gay characters and gay equality endorsement. The relationship was stronger for racial minority participants than for White participants, and for participants who had no or few interpersonal relationships with openly gay individuals than for participants who had more than three respective relationships. Results are discussed in terms of the parasocial contact hypothesis and television as an agent of social change.     

Building Your Licensing and Negotiation Skills Toolkit

Licensing and the negotiating of electronic resources can be a daunting task for librarians who lack the proper skill sets and are unfamiliar with the intricacies of publisher agreements. Claire Dygert broke down the individual elements of a standard licensing agreement and explained the importance of protecting the rights of libraries. By providing insight from her years of experience, librarians learned how to develop a support network, build confidence, and be more effective negotiators.     

Shifting the Perspective of the Research Librarian: A CoResearch Paradigm

This article proposes the coresearch engagement model (CoRE), which addresses how the academic research librarian can become a coresearch partner with any patron. The CoRE model is an interpersonal process and is founded upon the concepts of mutual respect, collaboration, reciprocity, and empowerment. Grounded in Howard Gardner’s multiple intelligences theory, Malcolm Knowles’ andragogical model, and guidelines from the Reference and User Services Association, CoRE has the potential to result in engagement for the librarian and patron. The CoRE model can be utilized in many ways including self-awareness and development for those who need and want to expand their abilities as a research librarian. It provides a theoretical framework and a knowledge base, in addition to giving a context for further development by expanding, comparing the related theories for further research, and implementing various applications suggested by this article.     

How the role of the independent editor is changing in relation to traditional and self‐publishing

This paper reports on a survey of editors undertaken during 2013. The survey asked about lifestyle and work, and in particular how these are changing with the growth of self‐publishing authors. This article reports on the changing opportunities for editorial work and the practices of independent editors, and how their working routines have changed over the past three years. It reveals a shift from working for traditional publishers towards working for new clients, including self‐publishing authors; relationships with traditional publishers are strained for a variety of reasons, and increasing satisfaction levels are discernible in relationships with experienced self‐publishers. The paper considers the consequences of editors' changing patterns of work and client base, and likely future outcomes. Areas for further close monitoring and research are suggested.     

Thermally multiplexed polymerase chain reaction

Amplification of multiple unique genetic targets using the polymerase chain reaction (PCR) is commonly required in molecular biology laboratories. Such reactions are typically performed either serially or by multiplex PCR. Serial reactions are time consuming, and multiplex PCR, while powerful and widely used, can be prone to amplification bias, PCR drift, and primer-primer interactions. We present a new thermocycling method, termed thermal multiplexing, in which a single heat source is uniformly distributed and selectively modulated for independent temperature control of an array of PCR reactions. Thermal multiplexing allows amplification of multiple targets simultaneously—each reaction segregated and performed at optimal conditions. We demonstrate the method using a microfluidic system consisting of an infrared laser thermocycler, a polymer microchip featuring 1 μl, oil-encapsulated reactions, and closed-loop pulse-width modulation control. Heat transfer modeling is used to characterize thermal performance limitations of the system. We validate the model and perform two reactions simultaneously with widely varying annealing temperatures (48 °C and 68 °C), demonstrating excellent amplification. In addition, to demonstrate microfluidic infrared PCR using clinical specimens, we successfully amplified and detected both influenza A and B from human nasopharyngeal swabs. Thermal multiplexing is scalable and applicable to challenges such as pathogen detection where patients presenting non-specific symptoms need to be efficiently screened across a viral or bacterial panel.     

Microfluidic chemical processing with on-chip washing by deterministic lateral displacement arrays with separator walls

We describe a microfluidic device for on-chip chemical processing, such as staining, and subsequent washing of cells. The paper introduces “separator walls” to increase the on-chip incubation time and to improve the quality of washing. Cells of interest are concentrated into a treatment stream of chemical reagents at the first separator wall for extended on-chip incubation without causing excess contamination at the output due to diffusion of the unreacted treatment chemicals, and then are directed to the washing stream before final collections. The second separator wall further reduces the output contamination from diffusion to the washing stream. With this approach, we demonstrate on-chip leukocyte staining with Rhodamine 6G and washing. The results suggest that other conventional biological and analytical processes could be replaced by the proposed device.
