Factors Determining Success In Practice

There are certain tangible, and many intangible factors which determine whether or not we become known as a successful practitioner. Of the tangible factors, professional knowledge and our particular practice territory are paramount. Professional knowledge, while it is not easy to acquire, is certainly made available to us while we are attending veterinary college. Experience is naturally an important adjunct to formal education, but this comes only with time. Formal education is merely a means by which we can take advantage of the experiences others have had. As far as professional knowledge is concerned, we usually have sufficient for successful practice

Closing Reading Achievement Gaps for Middle School Students

This research examined how self-efficacy, collective efficacy, and professional development compared between core content and special education middle school teachers working with middle school students in reading comprehension and fluency. Accordingly, no statistically significant difference in teacher self-efficacy between core content and special education teachers was discovered based on the ANOVA analysis results. An analysis of professional development and collective teacher efficacy showed mixed results with a negative relationship predicted between increased professional development hours for core content teachers. A predicted positive relationship existed with the number of professional development hours increasing for special education teachers. There was no statistically significant difference between core content and special education teachers’ numbers of professional development hours identified as low, medium, or high. The chi statistic showed that both populations of teachers had insufficient training

Evolution-guided functional analyses reveal diverse antiviral specificities encoded by IFIT1 genes in mammals.

IFIT (interferon-induced with tetratricopeptide repeats) proteins are critical mediators of mammalian innate antiviral immunity. Mouse IFIT1 selectively inhibits viruses that lack 2'O-methylation of their mRNA 5' caps. Surprisingly, human IFIT1 does not share this antiviral specificity. Here, we resolve this discrepancy by demonstrating that human and mouse IFIT1 have evolved distinct functions using a combination of evolutionary, genetic and virological analyses. First, we show that human IFIT1 and mouse IFIT1 (renamed IFIT1B) are not orthologs, but are paralogs that diverged >100 mya. Second, using a yeast genetic assay, we show that IFIT1 and IFIT1B proteins differ in their ability to be suppressed by a cap 2'O-methyltransferase. Finally, we demonstrate that IFIT1 and IFIT1B have divergent antiviral specificities, including the discovery that only IFIT1 proteins inhibit a virus encoding a cap 2'O-methyltransferase. These functional data, combined with widespread turnover of mammalian IFIT genes, reveal dramatic species-specific differences in IFIT-mediated antiviral repertoires

Magnetospheric eclipses in the double pulsar system J0737-3039

We argue that eclipses of radio emission from the millisecond pulsar A in the double pulsar system J0737-3039 are due to synchrotron absorption by plasma in the closed field line region of the magnetosphere of its normal pulsar companion B. A's radio beam only illuminates B's magnetosphere for about 10 minutes surrounding the time of eclipse. During this time it heats particles at r\gtrsim 10^9 cm to relativistic energies and enables extra plasma to be trapped by magnetic mirroring. An enhancement of the plasma density by a factor \sim 10^2 is required to match the duration and optical depth of the observed eclipses. The extra plasma might be supplied by a source near B through B\gamma pair creation by energetic photons produced in B's outer gap. Excitation of pairs' gyrational motions by cyclotron absorption of A's radio beam can result in their becoming trapped between conjugate mirror points in B's magnetosphere. Because the trapping efficiency decreases with increasing optical depth, the plasma density enhancement saturates even under steady state illumination. The result is an eclipse with finite, frequency dependent, optical depth. After illumination by A's radio beam ceases, the trapped particles cool and are lost. The entire cycle repeats every orbital period. We speculate that the asymmetries between eclipse ingress and egress result in part from the magnetosphere's evolution toward a steady state when illuminated by A's radio beam. We predict that A's linear polarization will vary with both eclipse phase and B's rotational phase.Comment: 8 pages, 1 figure, submitted to ApJ, references corrected, detectability of reprocessed emission revised, major conclusions unchange

Formation of an Academic Writing Group at Louisiana State University Libraries: Background, Guidelines and Lessons Learned

Producing high quality scholarly publications is a daunting task for many college and university librarians. In 2007, the LSU Libraries established a writing group to assist in this process. This four-member group makes itself available to review and critique manuscripts submitted by LSU librarians, most of whom are tenure-track. This paper examines the background, formation, and experiences-to-date of this group. Emphasis is placed on the particular characteristics of the LSU group, which make this group different from similar groups at other institutions. Thus, this paper includes, in its Appendices, practical materials such as forms for writers to use when submitting their works for review. It also includes the results of a small survey given to participants in order to gauge their satisfaction with the entire review process. The purpose for sharing this information is two-fold: first, to provide for the group itself a record of the group’s rationale and activities; and, second, to provide other college and university libraries with some useful tools if they are considering creating a similar program

Profit contribution information’s impact on internal integration

An exploratory quantitative study on the relationship between profit contribution information and firm-wide internal integration is presented. Specifically, the authors examine how profit contribution information availability impacts firm-wide internal integration and, subsequently, logistics performance. This study provides greater insight into the area; only a few studies have empirically examined the impact of profit contribution information within a firm. The primary implication is that firms should utilize specific types of information, i.e. profit contribution information, for making more informed operational and strategic decisions. The paper also underscores the managerial value of using profit contribution information in decision making and planning

Developing reverse logistics programs: A resource based view

Previous research proposes a six-process model for reverse logistics (RL) program design and execution. This manuscript advances RL related knowledge by incorporating the previous model into a broader theoretical framework, namely, the Resource Based View (RBV) of the firm. The current research employs exploratory techniques to investigate the applicability of RBV and its main tenants within the RL context. Based on in-depth interviews with 16 executives from seven different companies, the relationships among resources. RL capabilities, and RL competencies are explored

TESTING OF TMR SAND MANTIS FINAL REPORT

Screening tests of Sand Mantis candidate materials selected for erosion resistance have been completed. The results of this testing identified that over a relatively short period of operation (<1 hour), measurable erosion will occur in each of the candidate zoom tube materials given equal operating exposure. Additionally, this testing has shown that erosion of the rubber discharge hose directly downstream of the vehicle could be expected to limit the service life of the discharge hose. On the basis of these test results, SRNL recommends the following; {lg_bullet} redesign of critical system components (e.g., zoom tube, discharge hose) should be conducted to improve system characteristics relative to erosion and capitalize on the results of this testing, {lg_bullet} continued efforts to deploy the Sand Mantis should include testing to better define and optimize operating parameters, and gain an understanding of system dynamics, {lg_bullet} discontinue wear testing with the selected materials pending redesign of critical system components (1st recommendation) and inclusion of other candidate materials. The final selection of additional candidate materials should be made following design changes, but might include a Stellite alloy or zirconia
