Based Instruction

Decades of research has shown that television, as a medium for delivering instruction, is at least as effective as classroom lecture. Although many educators have expressed concern over the quality and frequency of student/teacher interaction available through televised courses, studies indicate that different learners may have distinct needs for varying types of interaction. As the use of videocassette recorders has become widespread possibilities have increased for new methods of video-based instruction. The increasing use of videocassettes for delivery of instruction has also raised questions for possible future research on how student use of this medium differs from broadcast television or live classroom lecture.

Engagement Interventions

Bearing in mind that agentic engagement has a recent history in comparison to the other types of engagement (behavioural, emotional and cognitive), this paper will present a theoretical review of this concept, including the reasons it has been denominated as the fourth type of student engagement. Agentic engagement is understood as the observable classroom event in which the learner constructively contributes to his/her learning and the instruction he/she receives (Reeve, 2012). The revision of research and theory on agentic engagement included in this paper supports the idea that it provides a consistent researchable field. Future research contributions may focus on (1) the disaffected face of agentic engagement, its conceptualization and its effects (Reeve & Tseng, 2011; Reeve, 2013) and (2) the understanding (description, typology and analysis) of students’ self-initiated contributions (proactive actions) in the classroom (Waring, 2011) in order to identify which strategies may facilitate students’ learning processes, teacher’s agentic engagement interventions, and student-teacher interaction.

Imaging Of Infection

Abstract Background The formation of infection threads in the symbiotic infection of rhizobacteria in legumes is a unique, fascinating, and poorly understood process. Infection threads are tubes of cell wall material that transport rhizobacteria from root hair cells to developing nodules in host roots. They form in a type of reverse tip-growth from an inversion of the root hair cell wall, but the mechanism driving this growth is unknown, and the composition of the thread wall remains unclear. High resolution, 3-dimensional imaging of infection threads, and cell wall component specific labelling, would greatly aid in our understanding of the nature and development of these structures. To date, such imaging has not been done, with infection threads typically imaged by GFP-tagged rhizobia within them, or histochemically in thin sections. Results We have developed new methods of imaging infection threads using novel and traditional cell wall fluorescent labels, and laser confocal scanning microscopy. We applied a new Periodic Acid Schiff (PAS) stain using rhodamine-123 to the labelling of whole cleared infected roots of Medicago truncatula; which allowed for imaging of infection threads in greater 3D detail than had previously been achieved. By the combination of the above method and a calcofluor-white counter-stain, we also succeeded in labelling infection threads and plant cell walls separately, and have potentially discovered a way in which the infection thread matrix can be visualized. Conclusions Our methods have made the imaging and study of infection threads more effective and informative, and present exciting new opportunities for future research in the area.

Multiple Probe

The ability to solve mathematical problems related to purchasing and personal finance is important in promoting skill generalization and increasing independence for individuals with moderate intellectual disabilities (IDs). Using a multiple probe across participant design, this study investigated the effects of modified schema-based instruction (MSBI) on personal finance problem solving skills, purchasing an item on sale or leaving a tip, and using a calculator or iDevice (i.e., iPhone or iPad) for three middle school students diagnosed with a moderate ID. The results showed a functional relation between MSBI using a calculator on the participant’s ability to solve addition and subtraction personal finance word problems and generalize to iDevices. The findings of this study provide several implications for practice and offer suggestions for future research.

The University

Students’ academic-related perceptions, beliefs, and strategies are fundamental elements that influence teaching and learning within colleges of agriculture. This study investigated students’ academic efficacy, academic self-handicapping, and skepticism about the relevance of school for future success at the University of Tennessee’s Herbert College of Agriculture. The students were academically efficacious, rarely self-handicapped, and did not doubt the relevance of their degree. In addition, a low negative association was found between academic efficacy and self-handicapping, a negligible relationship was found between academic efficacy and skepticism about the relevance of school for future success, and a moderate relationship was found between academic self-handicapping and skepticism about the relevance of school for future success. Therefore, instructors are encouraged to move past traditional lecture-based instruction and challenge their students at higher cognitive levels, which will allow students to realistically explore the complexities of agriculture. Furthermore, academic self-handicapping may be an indicator of lower academic efficacy and/or skepticism about the relevance of a student’s degree. Future research should further explore these relationships.

The Relationship

Service quality and customer satisfaction are vital concerns in service industries, particularly in the cruise industry. As such, the development of new methods for improving both is essential. A model of attitudes, intentions, and behaviors proposed by Bagozzi and refined by Schmit and Allscheid was tested to determine if employee job satisfaction and customer satisfaction were related constructs in the cruise industry. The hypothesized model did not account for the relationship between the measured and latent variables; however, a direct relationship between employee job satisfaction and customer satisfaction was found to exist (R2 = . 30). Implications for hospitality and travel organizations are discussed, and recommendations are made for future research.

Background: Synthetic polymers present disadvantages such as high cost, limited availability, safety concerns, environmental hazards and overtime accumulation in body. Lignin, an aromatic biopolymer, is highly abundant and offers various advantages including cost effectiveness, biocompatibility and biodegradability. It also possesses various pharmacological activities including antioxidant, antibacterial, anticancer and UV protection, thus lignin has become a popular biopolymer in recent years and is no more considered as bio-waste rather an extensive research is been carried out on developing it as drug carrier. Lignin also has non-biomedical applications including dispersing agents, surfactants, detergent/cleaning agents, energy storage, etc. Methods: This review compiles patents granted on production of technical lignin, different lignin therapeutic carriers and its biomedical and non-biomedical applications. The literature is collected from recent years including both articles as well as patents and is carefully analyzed and compiled in an easy to comprehend pattern for guiding future research. Results: The reviewed patents and articles highlighted the advancement made in lignin isolation and valorization. Numerous lignin nanoformulations as drug delivery agents or as standalone entities with various pharmacological actions like antibacterial, antioxidant or UV protectant have been reported. As well as industrial applications of lignin as adhesives, insulators or supercapacitors have also made lignin a biopolymer of choice. Conclusion: Lignin being a bio-inspired polymer has huge potential in commercial applications. New methods of lignin isolation from lignocellulosic biomass including physical pretreatments, solvent fraction, and chemical and biological pretreatment have been widely patented. Several micro/nano lignin formulations with improved and controllable reactivity like nanocontainers, nanocapsules, nanoparticles have also been reported recently. Also various pharmacological properties of lignin have also been explored, thus valorization of lignin is a hot topic of hour.
