Indiana Students Deserve High-Rated School Libraries

According to William Bainbridge, president of School Match, a firm that helps individuals and corporations evaluate 15,892 public school systems and 14,855 private schools; the level of expenditures for library and media services has the highest correlation with student achievement (New Jersey School Board Association Newsletter, 1995). Keith Curry Lance (2004) of the Colorado State Library found that schools with higher rated libraries have 10 to 18 percent better test scores than schools with lower rated libraries

Special Educators and Mathematics Phobia: An Initial Qualitative Investigation

Special educators are uniquely challenged to be content experts in all curricular areas, including mathematics, since students in their case loads may require academic instruction in any area. However, special educators with math phobia may be limited in their ability to provide effective instruction to their students with mathematical deficits and/or needs, and may experience additional challenges in their professional and personal lives. This qualitative study sought to better understand the nature of math phobia in two special educators through extensive interviews, journaling, and observations in math experiences, with a number of primary themes identified. Several potential resolutions for the issues emerging from math phobia in special educators are identified and discussed

Mentors Increasing Special Education Retention

Lack of effective professional mentoring and minimal ongoing support programs have been suggested as two primary contributors to the chronic shortages of special education teachers. Few programs have been designed to address these specific causes. In this article we describe TATERS, a partnership between a university special educator preparation program, a state Department of Education, and district level administrations designed to (a) develop effective mentoring systems, and (b) strengthen training and recruitment of preservice and new special education teachers, especially in rural areas

RNA dysregulation in models of frontotemporal dementia and amyotrophic lateral sclerosis

Amyotrophic Lateral Sclerosis (ALS) and Frontotemporal dementia (FTD) are two rare but devastating neurodegenerative diseases that share pathological features and genetic factors. A central question in both diseases is the role of the RNA-binding proteins transactive response DNA-binding protein 43kDa (TDP-43) and fused in sarcoma (FUS). These proteins play a vital role in RNA regulation in all cells but in diseased neurons they alter their cellular localisation to form potentially pathogenic aggregates. This process can be linked to rare genetic mutations in the TARDBP and FUS genes, although most cases of ALS and FTD have no known genetic cause. My work uses the revolutionary technology of RNA sequencing to measure and compare gene expression and RNA splicing in different cellular and animal models of sporadic and genetic disease. Here I present the results of four studies that investigate the biology of TDP-43 and FUS, assessing both their normal cellular roles and the impact of rare disease-causing mutations. In these projects I analyse RNA sequencing data to discover novel gene expression and RNA splicing phenomena. This includes the repression of cryptic splicing by TDP-43 but not FUS, the progressive downregulation of mitochondrial and ribosomal transcripts in a mouse model of FUS ALS, a gain of splicing function by TDP-43 mutations affecting constitutive exon splicing, and widespread changes in intron retention caused by FUS knockout or aggressive FUS mutations. I also discover a novel mechanism for how FUS might regulate its own translation. This work expands on what is currently known about the roles in RNA regulation for TDP- 43 and FUS and provides new avenues for understanding both the causes and progression of ALS and FTD

The Oral and Skin Microbiomes of Captive Komodo Dragons Are Significantly Shared with Their Habitat.

Examining the way in which animals, including those in captivity, interact with their environment is extremely important for studying ecological processes and developing sophisticated animal husbandry. Here we use the Komodo dragon (Varanus komodoensis) to quantify the degree of sharing of salivary, skin, and fecal microbiota with their environment in captivity. Both species richness and microbial community composition of most surfaces in the Komodo dragon's environment are similar to the Komodo dragon's salivary and skin microbiota but less similar to the stool-associated microbiota. We additionally compared host-environment microbiome sharing between captive Komodo dragons and their enclosures, humans and pets and their homes, and wild amphibians and their environments. We observed similar host-environment microbiome sharing patterns among humans and their pets and Komodo dragons, with high levels of human/pet- and Komodo dragon-associated microbes on home and enclosure surfaces. In contrast, only small amounts of amphibian-associated microbes were detected in the animals' environments. We suggest that the degree of sharing between the Komodo dragon microbiota and its enclosure surfaces has important implications for animal health. These animals evolved in the context of constant exposure to a complex environmental microbiota, which likely shaped their physiological development; in captivity, these animals will not receive significant exposure to microbes not already in their enclosure, with unknown consequences for their health. IMPORTANCE Animals, including humans, have evolved in the context of exposure to a variety of microbial organisms present in the environment. Only recently have humans, and some animals, begun to spend a significant amount of time in enclosed artificial environments, rather than in the more natural spaces in which most of evolution took place. The consequences of this radical change in lifestyle likely extend to the microbes residing in and on our bodies and may have important implications for health and disease. A full characterization of host-microbe sharing in both closed and open environments will provide crucial information that may enable the improvement of health in humans and in captive animals, both of which experience a greater incidence of disease (including chronic illness) than counterparts living under more ecologically natural conditions

Improved bacterial 16S rRNA gene (V4 and V4-5) and fungal internal transcribed spacer marker gene primers for microbial community surveys

The definitive version was published in mSystems 1 (2015): e00009-15, doi:10.1128/mSystems.00009-15.Designing primers for PCR-based taxonomic surveys that amplify a broad range of phylotypes in varied community samples is a difficult challenge, and the comparability of data sets amplified with varied primers requires attention. Here, we examined the performance of modified 16S rRNA gene and internal transcribed spacer (ITS) primers for archaea/bacteria and fungi, respectively, with nonaquatic samples. We moved primer bar codes to the 5′ end, allowing for a range of different 3′ primer pairings, such as the 515f/926r primer pair, which amplifies variable regions 4 and 5 of the 16S rRNA gene. We additionally demonstrated that modifications to the 515f/806r (variable region 4) 16S primer pair, which improves detection of Thaumarchaeota and clade SAR11 in marine samples, do not degrade performance on taxa already amplified effectively by the original primer set. Alterations to the fungal ITS primers did result in differential but overall improved performance compared to the original primers. In both cases, the improved primers should be widely adopted for amplicon studies.J.A.F. and A.P. are supported by the Gordon and Betty Moore Foundation (GMBF3779) and NSF grant 1136818.
