Using Web 2.0 Tools such as Google Apps in Library Instruction Sessions with Non-Traditional Students

Much has been written about traditional undergraduate students and their familiarity with Web 2.0 tools. But how “tech savvy” are non-traditional students? How can tools such as Google Apps be used in library instruction with these students? Troy University Montgomery Campus serves an especially diverse student body; roughly two-thirds are adult, non-traditional students (average age of 28). Librarians on this campus surveyed students in library instruction classes to find out their knowledge and use of Web 2.0 technologies such as social networking, image and video sharing, collaborative authoring tools, communication tools, social games/spaces and blogs. Survey results show that many of the students not only had never used these tools, but they had never even heard of them. As a result of these findings, librarians now incorporate some of these Web 2.0 technologies in their library instruction sessions. Presenters will discuss how librarians introduce students to Web 2.0 tools in library instruction and explain how online tools such as Google Apps can be used not only as a collaborative authoring tool for students, but also for librarians designing instruction sessions. For example, class assignments using documents, spreadsheets, and presentations can be created and shared, opened, and edited by multiple users at the same time. Students can be surveyed and their feedback results sent to a spreadsheet. PowerPoint slides can be created and published to the web for viewing at any time. The presenters will conclude by sharing both the benefits and drawbacks of using Google Apps in library instruction sections

Creating a Culture of Mentoring @ Your Library

The need to find and retain high quality leadership for libraries is one of the top seven issues for academic libraries. With a significant percentage of librarians planning to retire in the next decade, retaining professionals is imperative. Librarians must not only be retained, but mentored and developed for future leadership roles in the academic library community (Hisle, 2002). Creating a “culture of mentoring” helps the organization, individuals in the organization, and those with whom they interact. This culture provides integrity (accountability) throughout the organization, and opportunities for learning, for feedback and for improvement of performance throughout the organization. Libraries are using mentoring to orient new librarians, to assist them through the promotion and tenure process, and to provide information to librarians interested in advancement

The PCL–R and capital sentencing: A commentary on “Death is different” DeMatteo et al. (2020a).

DeMatteo et al. (2020a) published a Statement in this journal declaring that the Psychopathy Checklist-Revised (PCL-R) “cannot and should not” be used in U.S. capital-sentencing cases to assess risk for serious institutional violence. Their stated concerns were the PCL-R’s “imperfect interrater reliability,” its “variability in predictive validity,” and its prejudicial effects on the defendant. In a Cautionary Note, we (Olver et al., 2020) raised questions about the Statement’s evaluation of the PCL-R’s psychometric properties, presented new data, including a meta-meta-analysis, and argued that the evidence did not support the Statement’s declaration that the PCL-R “cannot” be used in high stakes contexts. In their reply, titled “Death is Different,” DeMatteo et al. (2020b) concurred with several points in our Cautionary Note, disputed others, asserted that we had misunderstood or mischaracterized their Statement, and dismissed our new data and comments as irrelevant to the Statement’s purpose. This perspective on our commentary is inimical to balanced academic discourse. In this article, we contend that DeMatteo et al. (2020b) underestimated the reliability and predictive validity of PCL-R ratings, overestimated the centrality of the PCL-R in sentencing decisions, and underplayed the importance of other factors. Most of their arguments depended on sources other than capital cases, including mock trials, Sexually Violent Predator (SVP) hearings, and studies that included the prediction of general violence. We conclude that the rationale for the bold “cannot and should not” decree is open to debate and in need of research in real-life venues

Reliability and validity of the Psychopathy Checklist-Revised in the assessment of risk for institutional violence: A cautionary note on DeMatteo et al. (2020).

A group of 12 authors (GA) shared a statement of concern (SoC) warning against the use of the Hare Psychopathy Checklist-Revised (PCL-R; Hare, 1991, 2003) to assess risk for serious institutional violence in US capital sentencing cases (DeMatteo et al., 2020). Notably, the SoC was not confined to capital sentencing issues, but included institutional violence in general. Central to the arguments presented in the SoC was that the PCL-R has poor predictive validity for institutional violence and also inadequate field reliability. The GA also identified important issues about the fallibility and inappropriate use of any clinical/forensic assessments, questionable evaluator qualifications, and their effects on capital sentencing decisions. However, as a group of forensic academics, researchers, and clinicians, we are concerned that the PCL-R represents a psycholegal red herring, while the SoC did not address critical legislative, systemic, and evaluator/rating issues that affect all risk assessment tools. We contend that the SoC’s literature review was selective and that the resultant opinions about potential uses and misuses of the PCL-R were ultimately misleading. We focus our response on the evidence and conclusions proffered by the GA concerning the use of the PCL-R in capital and other cases. We provide new empirical findings regarding the PCL-R’s predictive validity and field reliability to further demonstrate its relevance for institutional violence risk assessment and management. We further demonstrate why the argument that group data cannot be relevant for single-case assessments is erroneous. Recommendations to support the ethical and appropriate use of the PCL-R for risk assessment are provided

Racial/ethnic and sexual behavior disparities in rates of sexually transmitted infections, San Francisco, 1999-2008

<p>Abstract</p> <p>Background</p> <p>Racial/ethnic minorities and men who have sex with men (MSM) represent populations with disparate sexually transmitted infection (STI) rates. While race-specific STI rates have been widely reported, STI rates among MSM is often challenging given the absence of MSM population estimates. We evaluated the race-specific rates of chlamydia and gonorrhea among MSM and non-MSM in San Francisco between 1999-2008.</p> <p>Methods</p> <p>2000 US Census data for San Francisco was used to estimate the number of African-American, Asian/Pacific Islander, Hispanic, and white males. Data from National HIV Behavioral Surveillance (NHBS) MSM 1, conducted in 2004, was used to estimate the total number of MSM in San Francisco and the size of race/ethnic sub-populations of MSM. Non-MSM estimates were calculated by subtracting the number of estimated MSM from the total number of males residing in San Francisco. Rates of MSM and non-MSM gonorrhea and chlamydia reported between 1999 and 2008 were stratified by race/ethnicity. Ratios of MSM and non-MSM rates of morbidity were calculated by race/ethnicity.</p> <p>Results</p> <p>Between 1999-2008, MSM accounted for 72% of gonorrhea cases and 51% of chlamydia cases. Throughout the study period, African-American MSM had the highest chlamydia rate with 606 cases per 100,000 in 1999 increasing to 2067 cases per 100,000 in 2008. Asian/Pacific Islander MSM consistently had the lowest rate among MSM with1003 cases per 100,000 in 2008. The ratio of MSM/non-MSM for chlamydia was highest among whites 11.6 (95% CI: 8.8-14.4) and Asian/Pacific Islanders 8.6 (95% CI: 6.2-11), and lowest among African-Americans 1.53 (95% CI: 1.2-1.9) and Hispanics 4.43 (95% CI: 2.8-6.0). Gonorrhea rates were similar for African-American, white, and Hispanic MSM between 2137-2441 cases per 100,000 in 2008. Asian/Pacific Islander MSM had the lowest gonorrhea rate with 865 cases per 100,000 in 2008. The ratio of MSM/non-MSM for gonorrhea was highest among whites 11.6 (95% CI: 8.8-14.4) and Asian/Pacific Islanders 8.6 (95% CI: 6.2-11), and lowest among African-Americans 1.53 (95% CI: 1.2-1.9) and Hispanics 4.43 (95% CI: 2.8-6.0).</p> <p>Conclusions</p> <p>For all racial/ethnic groups in San Francisco, MSM carried a substantially higher burden of STIs compared to non-MSM except among African-American men. These racial and sexual behavior disparities warrant further public health attention and resources.</p

ROSAT Observations of Solar Wind Charge Exchange with the Lunar Exosphere

We analyze the ROSAT PSPC soft X-ray image of the Moon taken on 29 June 1990 by examining the radial profile of the count rate in three wedges, two wedges (one north and one south) 13-32 degrees off (19 degrees wide) the terminator towards the dark side and one wedge 38 degrees wide centered on the anti-solar direction. The radial profiles of both the north and the south wedges show substantial limb brightening that is absent in the 38 degree wide antisolar wedge. An analysis of the count rate increase associated with the limb brightening shows that its magnitude is consistent with that expected due to solar wind charge exchange (SWCX) with the tenuous lunar atmosphere. Along with Mars, Venus, and Earth, the Moon represents another solar system body at which solar wind charge exchange has been observed. This technique can be used to explore the solar wind-lunar interaction

Microsporidia – Emergent Pathogens in the Global Food Chain

Intensification of food production has the potential to drive increased disease prevalence in food plants and animals. Microsporidia are diversely distributed, opportunistic, and density-dependent parasites infecting hosts from almost all known animal taxa. They are frequent in highly managed aquatic and terrestrial hosts, many of which are vulnerable to epizootics, and all of which are crucial for the stability of the animal-human food chain. Mass rearing and changes in global climate may exacerbate disease and more efficient transmission of parasites in stressed or immune-deficient hosts. Further, human microsporidiosis appears to be adventitious and primarily associated with an increasing community of immune-deficient individuals. Taken together, strong evidence exists for an increasing prevalence of microsporidiosis in animals and humans, and for sharing of pathogens across hosts and biomes.This is the publisher’s final pdf.
