Medication adherence and glycemic control in patients with psychotic disorders in The Veterans Affairs healthcare system
Nelson,Leigh Anne; Graham,Maqual R.; Lindsey,Cameron C.; Rasu,Rafia S.;
Pharmacy Practice (Internet) , 2011, DOI: 10.4321/S1886-36552011000200001
Abstract: objective: to compare antihyperglycemic medication adherence and glycemic control between individuals with schizophrenia and related psychotic disorders and a nonpsychiatric comparison group. methods: this was a retrospective medical record review. a total of 124 subjects with diabetes (62 patients with schizophrenia or a related psychotic disorder and 62 randomly selected, age-matched patients without a psychiatric illness) receiving their medical and psychiatric care exclusively through the kansas city veterans affairs healthcare system during 2008 were included in the study. adherence to antihyperglycemic and antipsychotic medication was determined by refill records obtained through the computerized patient record system to calculate the cumulative mean gap ratio. hemoglobin a1c values were utilized to compare glycemic control between groups and compared to glycemic goals established by diabetes treatment guidelines. results: antihyperglycemic medication adherence was poor for both groups as approximately 60% of the psychotic disorder group and 75% of the nonpsychiatric comparison group were without antihyperglycemic medication for greater than 30 days during the 12-month period but adherence did not differ between the groups (p=0.182). antipsychotic adherent subjects (≥80% adherent) were more likely to be adherent to their antihyperglycemic medication (p=0.0003). there were no significant differences between groups in glycemic control. conclusion: antihyperglycemic medication adherence and glycemic control was less than optimal for both groups. there were no significant differences in antihyperglycemic medication adherence and glycemic control between patients with a psychotic disorder and those without a psychiatric illness.

A Use-Based Measure of Accessibility to Linear Features to Predict Urban Trail Use
John R. Ottensmann,Greg Lindsey
Journal of Transport and Land Use , 2008,
Abstract: The standard Hansen measure of accessibility is extended to provide a use-based measure of accessibility reflecting the elasticity of use with respect to the level of provision of facilities. This is further extended to provide a measure of accessibility to linear features, such as trails (as opposed to features at point locations such as parks and libraries). Results from a survey on the use of urban trails in Indianapolis, Indiana are used to test the ability of this accessibility measure to predict trail use. The use-based measure of accessibility to linear features provides better predictions of use and more consistent estimates of the effects of distance and level of facility provision on trail use.
Schur Multipliers of Nilpotent Lie Algebras
Lindsey R. Bosko,Ernie L. Stitzinger
Mathematics , 2011,
Abstract: We consider the Schur multipliers of finite dimensional nilpotent Lie algebras. If the algebra has dimension greater than one, then the Schur multiplier is non-zero. We give a direct proof of an upper bound for the dimension of the Schur multiplier as a function of class and the minimum number of generators of the algebra. We then compare this bound with another known bound.
The Impact of Cattle Grazing in High Elevation Sierra Nevada Mountain Meadows over Widely Variable Annual Climatic Conditions  [PDF]
Lindsey Myers, Brenda Whited
Journal of Environmental Protection (JEP) , 2012, DOI: 10.4236/jep.2012.328097
Abstract: The impact of summer cattle grazing on water quality during three very different climatic years in the Sierra Nevada was investigated. Water year 2009 had near normal precipitation; 2010 had late precipitation and snowmelt; and 2011 had 150% above normal precipitation. Surface waters were tested for pathogenic bacteria indicators fecal coliform, E. coli, and total coliform before and after cattle were released onto summer grazing allotments. Water samples were collected from meadow stream sites up to 6 weeks before and up to 6 weeks after cattle grazing began. Streams passing through ungrazed meadow served as controls. Eight sample sites were between 1694 m and 2273 m in elevation; one site was lower at 1145 m in elevation. Samples were transported within 6 hours to a water analysis laboratory, where samples were analyzed following standardized laboratory methods. Results showed that individual site and total mean concentrations of E. coli in surface waters were within regulatory standards before cattle arrived during each of the 3 study years. After the beginning of grazing, mean E. coli counts increased as follows: 2009 from 8 to 240 CFU/100mL, 2010 from 7 to 561 CFU/10mL; 2011 from 7 to 657 CFU/100mL (p < 0.05 all years). Total coliform bacteria and fecal coliform concentrations showed the same pattern. This study shows that cattle grazing in the high elevation Sierra Nevada results in a significant increase in indicator bacteria. This impact on the watersheds occurs despite widely variable annual climatic conditions.
Photonic Communications and Quantum Information Storage Capacities  [PDF]
William C. Lindsey
Optics and Photonics Journal (OPJ) , 2013, DOI: 10.4236/opj.2013.32B032
Abstract:

This paper presents photonic communications and data storage capacitates for classical and quantum communications over a quantum channel. These capacities represent a generalization of Shannon’s classical channel capacity and coding theorem in two ways. First, it extends classical results for bit communication transport to all frequencies in the electromagnetic spectrum. Second, it extends the results to quantum bit (qubit) transport as well as a hybrid of classical and quantum communications. Nature’s limits on the rate at which classical and/or quantum information can be sent error-free over a quantum channel using classical and/or quantum error-correcting codes are presented as a function of the thermal background light level and Einstein zero-point energy. Graphical results are given as well as numerical results regarding communication rate limits using Planck’s natural frequency and time-interval units!

Gender Differences: Mortgage Credit Experience  [PDF]
Debby Lindsey-Taliefero
Modern Economy (ME) , 2015, DOI: 10.4236/me.2015.69093
Abstract: This study examined gender differences in the mortgage credit experience. Home Mortgage Disclosure Data Act (HMDA) data along with Lending PatternsTM generated rates for originations, denials, and fallouts from 2004 to 2013. The gender effect on these rates was examined for statistical differences using the independent t-test, ANOVA, and one sample t-test. Across the country, the results showed no statistical gender effect on origination, denial or fallout rates in the post-housing crisis era. Within the race, this relationship held up, with exclusions. The white females had a lower fallout rate than white males, and Asian females had a higher denial rate than Asian males. Within gender, controlling for race, white females had higher origination and lower denial rates than Black, Hispanic, and Native Americans but were not statistically different from Asian females. Comparing white males to females by race, the results indicated that 53% of the time white males had higher origination, lower denial, or lower fallout rates than females. While 40% of the time, the white male’s mortgage experience was not statistically different from females. Seven percent of the time the white male’s origination rate was lower than white females. In the final analysis, at no time did minority females have a better mortgage experience than white males, but they did 33% of the time experience no statistical difference. Given these points, the applicant’s gender had less of an effect on the mortgage credit experience than the applicant’s race.
Teachers Creating Effective Learning Experiences for Indigenous Learners  [PDF]
Lindsey Conner, Judith Bennetts
Creative Education (CE) , 2018, DOI: 10.4236/ce.2018.96074
Abstract: “Recently professional learning and development has turned a corner. Teachers as leaders of learning have realized that they can be agents of change within their classrooms by focusing on quite specific teaching changes to improve outcomes for their learners” (Conner, 2015: p. 7). This paper provides examples of how teachers were challenged to link changes in their practice to include good principles of indigenous pedagogies (through participating in cycles of teaching and inquiry), to changes in students’ outcomes, which has rarely been reported previously. Vignettes of changes teachers made to their teaching were gathered as they responded to reflections and support from mentors and used student achievement data as tools for inquiry. Teachers were provoked to be more aware of the importance of evidence-informed critical reflection on pedagogical development that was appropriate for indigenous students. We provide an overall analysis and vignette examples to illustrate the emerging themes which were: the development of positive professional relationships (mentor-teacher, teacher-teacher and teacher-student), developing pedagogical knowledge that was appropriate for indigenous students that was also informed by seeking student and whānau (family) voice or feedback to inform changes to teaching.
Factors Impacting Corn (Zea mays L.) Establishment and the Role of Uniform Establishment on Yield  [PDF]
Lindsey Novak, Joel Ransom
Agricultural Sciences (AS) , 2018, DOI: 10.4236/as.2018.910092
Abstract: Information from actual farm fields can help corn producers understand the value and importance of establishing uniform crop emergence and within-row plant spacing. Thirty-eight fields planted with corn (Zea mays L.) by North Dakota producers were evaluated to determine the effects of uneven plant emergence timing and within-row plant space variability, as well as identifying contributing factors. Rows within a planter’s width with the most variability yielded 6% less than the least variable rows. Individual ear weights decreased as the number of days after normal emergence (date when 50% of plant stand emerged) increased. Ears next to within-row gaps (>30.5 cm) weighed 11% more than the normally spaced plants. Combined ears from both plants situated <5.1 cm apart weighed 36% more than from a single ear from normally spaced plants. Surface residue and planting speed impacted stand establishment variability more often than other factors measured. Producers should assess each field environment individually in order to identify best practices to achieve uniform stand establishment.
Neuronal Mechanisms of Voice Control Are Affected by Implicit Expectancy of Externally Triggered Perturbations in Auditory Feedback
Oleg Korzyukov, Lindsey Sattler, Roozbeh Behroozmand, Charles R. Larson
PLOS ONE , 2012, DOI: 10.1371/journal.pone.0041216
Abstract: Accurate vocal production relies on several factors including sensory feedback and the ability to predict future challenges to the control processes. Repetitive patterns of perturbations in sensory feedback by themselves elicit implicit expectations in the vocal control system regarding the timing, quality and direction of perturbations. In the present study, the predictability of voice pitch-shifted auditory feedback was experimentally manipulated. A block of trials where all pitch-shift stimuli were upward, and therefore predictable was contrasted against an unpredictable block of trials in which the stimulus direction was randomized between upward and downward pitch-shifts. It was found that predictable perturbations in voice auditory feedback led to a reduction in the proportion of compensatory vocal responses, which might be indicative of a reduction in vocal control. The predictable perturbations also led to a reduction in the magnitude of the N1 component of cortical Event Related Potentials (ERP) that was associated with the reflexive compensations to the perturbations. We hypothesize that formation of expectancy in our study is accompanied by involuntary allocation of attentional resources occurring as a result of habituation or learning, that in turn trigger limited and controlled exploration-related motor variability in the vocal control system.
