Support for the beginning special educator through high quality mentoring

Approximately 50% of school districts across the nation have reported barriers in obtaining highly qualified teachers (U.S. Department of Education, 2009). Beginning special education teachers report that they often feel they lack the prerequisite skills for working with their students, particularly students from culturally and linguistically diverse backgrounds. Special educators often feel unsupported and overwhelmed by the continuous changes in districts related to No Child Left Behind (NCLB). Additionally, nationwide alternative programs are being developed as a means for special education teachers to clear their credential outside of the university setting. The need for support of these teachers in today\u27s schools is critical. This article highlights best practices for development of high quality mentoring for beginning special education teachers based on meaningful relationships, guidance, and reflective practices

Options for organization and operation of space applications transfer centers

The benefits of developing regional facilities for transfer of NASA developed technology are discussed. These centers are designed to inform, persuade, and serve users. Included will be equipment for applications and demonstrations of the processes, a library, training facilities, and meeting rooms. The staff will include experts in the various techniques, as well as personnel involved in finding and persuading potential users

Energy Conservation in Uniroyal, Inc.

In the last year, rapid developments have led to the establishment of industry conservation goals and monitoring by the Department of Commerce and the Federal Energy Administration via the various industry associations. Since 1972, Uniroyal has progressed more than half way toward the 1980 goal of 15% established for the rubber and chemical industries. This paper will describe details of the program with emphasis on new input, such as the computerized tracking method now in use. Plant studies have provided an assessment of base loads vs. process loads, important when considering unit energy consumption. These vary, particularly with the climate and with the ratio of electrical to fuel energy inputs. Also, in-plant metering of steam has produced some surprises. Priorities for projects and lines of attack for conservation depend upon such analyses. Of great importance is the energy content of raw materials and programs to reduce or recycle rejected portions. A study of organization for conservation in various other companies was made to develop recommendations for improving the Uniroyal program. A composite of the best features will be presented

Depressive symptoms and quality of life in people with age-related macular degeneration

Purpose: To examine quality of life and associated factors in people with Age-Related Macular Degeneration (AMD). Methods: One hundred and forty-five AMD participants (mean age 78.0 +/- 7.7 years) and 104 age- and gender- matched controls (mean age 78.1 +/- 5.8 years) comprised the study populations for this case-control study. Depressive symptoms were measured with the Goldberg Anxiety and Depression (GAD) scale; general health and daily functioning was assessed with the Medical Outcomes Study Short Form 36 (SF-36) and questions relating to assistance required for daily living activities. Results: People with AMD performed more poorly than controls on the GAD depression scale, and physical functioning subscale of SF-36. 44.4% of people with AMD had clinically significant depressive symptoms compared to 17.5% of controls (p < 0.001). Multiple regression analysis revealed that AMD was independently associated with depressive symptoms and a path model indicated that AMD led to depressive symptoms both directly and indirectly via reduced general health and social functioning. Conclusion: Psychological and functional outcome measures are reduced in people with AMD. Earlier recognition and treatment of depressive symptoms in people with AMD may be crucial to maintaining quality of life in this group

Shedding light on melanins within in situ human eye melanocytes using 2-photon microscopy profiling techniques.

Choroidal melanocytes (HCMs) are melanin-producing cells in the vascular uvea of the human eye (iris, ciliary body and choroid). These cranial neural crest-derived cells migrate to populate a mesodermal microenvironment, and display cellular functions and extracellular interactions that are biologically distinct to skin melanocytes. HCMs (and melanins) are important in normal human eye physiology with roles including photoprotection, regulation of oxidative damage and immune responses. To extend knowledge of cytoplasmic melanins and melanosomes in label-free HCMs, a non-invasive 'fit-free' approach, combining 2-photon excitation fluorescence lifetimes and emission spectral imaging with phasor plot segmentation was applied. Intracellular melanin-mapped FLIM phasors showed a linear distribution indicating that HCM melanins are a ratio of two fluorophores, eumelanin and pheomelanin. A quantitative histogram of HCM melanins was generated by identifying the image pixel fraction contributed by phasor clusters mapped to varying eumelanin/pheomelanin ratio. Eumelanin-enriched dark HCM regions mapped to phasors with shorter lifetimes and longer spectral emission (580-625 nm) and pheomelanin-enriched lighter pigmented HCM regions mapped to phasors with longer lifetimes and shorter spectral emission (550-585 nm). Overall, we demonstrated that these methods can identify and quantitatively profile the heterogeneous eumelanins/pheomelanins within in situ HCMs, and visualize melanosome spatial distributions, not previously reported for these cells

Intravenous infusion of magnesium sulfate and its effect on horses with trigeminal-mediated headshaking.

BackgroundTrigeminal-mediated headshaking results from low-threshold firing of the trigeminal nerve resulting in apparent facial pain. Magnesium may have neuroprotective effects on nerve firing that potentially dampen signs of neuropathic pain. This hypothesis has not been investigated in horses with trigeminal-mediated headshaking.ObjectiveTo investigate head-shaking behavior in affected horses after IV magnesium sulfate infusion.AnimalsSix geldings with trigeminal-mediated headshaking.MethodsProspective randomized crossover study. Horses were controlled for diet and infused IV with 5% dextrose solution (DS; control solution at 2 mL/kg body weight [BW]) and MgSO4 50% solution (MSS at 40 mg/kg BW). Head-shaking behavior was recorded at times T0 (baseline, before infusion) and T15, T30, T60, and T120 minutes post-infusion. Venous blood variables such as pH, HCO3 - , standard base excess (SBE), Na+ , Cl- , K+ , Ca2+ , Mg2+ , total magnesium (tMg), glucose, and lactate were measured; strong ion difference (SID) and anion gap (AG) were calculated for each time point.ResultsBlood variables including pH, Na+ , Cl- , K+ , SID, AG, lactate, Ca2+ , tMg, and Mg2+ had significant changes with MSS as compared to DS treatment. Glucose, SBE, and HCO3 - did not have significant changes. A 29% reduction in head-shaking rate occurred after MSS treatment but no change occurred after DS treatment.Conclusions and clinical importanceAdministration of MSS IV increased plasma total and ionized magnesium concentrations and significantly decreased head-shaking behavior in horses with trigeminal-mediated headshaking
