Ten polymorphic microsatellite primers in the tropical tree caimito, Chrysophyllum cainito (Sapotaceae).

UnlabelledPremise of the studyWe developed microsatellite primers for the tropical tree Chrysophyllum cainito (Sapotaceae) to determine the native range of the species, investigate the origin of cultivated populations, and examine the partitioning of genetic diversity in wild and cultivated populations. •Methods and resultsWe developed 10 polymorphic primers from C. cainito genomic DNA libraries enriched for di-, tri-, and tetranucleotide repeat motifs. The loci amplified were polymorphic in samples collected from Jamaica and Panama. The number of alleles per locus ranged from two to 10 and three to 12, while observed heterozygosities ranged from 0.074 to 0.704 and 0.407 to 0.852 in Jamaica and Panama, respectively. •ConclusionsThe microsatellite primers will be useful in future population genetic studies as well as those aimed at understanding the geographic origin(s) of wild and cultivated populations

The Whiteness of Silence: A Critical Autoethnographic Tale of a Strategic Rhetoric

Nakayama and Krizeck’s essay, “A Strategic Rhetoric of Whiteness” offers an understanding of Whiteness as cultural praxis operating beyond the narrow understanding of mere skin color. While scholars have added valuable contributions to the study of Whiteness, the discussion of the “strategic rhetoric” still lacks examples of embodiment. This essay seeks to demonstrate the deployment of Whiteness by describing a specific moment in which I was complicit in the deployment of Whiteness using the strategy of silence. This essay enumerates the machinations of Whiteness hidden in a seemingly mundane performance and contributes to an ongoing conversation about problematizing Whiteness

Comparison of modal analysis results of laser vibrometry and nearfield acoustical holography measurements of an aluminum plate

Noise and vibration has long been sought to be reduced in major industries: automotive, aerospace and marine to name a few. Products must be tested and pass certain levels of federally regulated standards before entering the market. Vibration measurements are commonly acquired using accelerometers; however limitations of this method create a need for alternative solutions. Two methods for non-contact vibration measurements are compared: Laser Vibrometry, which directly measures the surface velocity of the aluminum plate, and Nearfield Acoustic Holography (NAH), which measures sound pressure in the nearfield, and using Green’s Functions, reconstructs the surface velocity at the plate. The surface velocity from each method is then used in modal analysis to determine the comparability of frequency, damping and mode shapes. Frequency and mode shapes are also compared to an FEA model. Laser Vibrometry is a proven, direct method for determining surface velocity and subsequently calculating modal analysis results. NAH is an effective method in locating noise sources, especially those that are not well separated spatially. Little work has been done in incorporating NAH into modal analysis

Intergroup Dialogue as Praxis for Engaging the Intercultural World

Intergroup Dialogue (IGD) is a formalized program that centers dialogue among students in the classroom. The IGD program uses Martin Buber’s (1970) concept of dialogue, and this semester-long project situates dialogue as a useful addition to an Intercultural Communication course. Bringing components of a formal dialogue program into the classroom as a part of a course allows students to engage with difficult topics, such as race, gender, sexual orientation, class, and ability, among others, in a way that helps students process and better understand perspectives different from their own. This essay provides specific opportunities for meaningful dialogue and concludes an evaluation of our semester-long project and the lessons learned along the way

The Effect of Instruction Differentiation in Preventive Classroom Management Strategies on Early Childhood and Elementary Preservice Teachers' Selected Behaviors in a Music Integration Course

The purpose of this study was to investigate the effect of instruction differentiation in preventive classroom management strategies on early childhood and elementary preservice teachers’ selected behaviors during assigned classroom teaching of music instruction to peers. Participants were early childhood and elementary preservice teachers (N = 7) enrolled in a music integration course at a Midwestern university. This investigation constituted a two-factor within subjects design. The first independent variable was instruction in preventive classroom management which had three conditions: lecture, individual practice, and demonstration practice; the second independent variable was lesson type which had three levels: song/chant, listening, and movement. The dependent variable was the number of selected behaviors (verbal cues, physical proximity, model correct student behavior) displayed by the participants across three eight-minute microteaching sessions. Primary findings included: (a) no statistically significant main effect for treatment condition; (b) a significant main effect for lesson type; (c) a significant main effect for microteaching session; (d) no significant difference among lecture, individual practice, and demonstration practice conditions; (e) a significant difference between listening and movement lessons; (f) no significant difference between song/chant and movement lessons; (g) a significant difference between microteaching session one and three. Anecdotal data and open-ended responses indicated that participants found their participation in this investigation to be beneficial with respect to gaining knowledge of preventive classroom management and experiencing hands-on practice with these strategies. The participants also noted the immediacy and transferability of preventive classroom management strategies to various settings outside of their teacher preparation programs. Results were discussed in terms of (a) limitations of the study; (b) general outcomes; (c) implications and suggestions for future investigations; and (d) considerations for early childhood, elementary, and music education research

Health Literacy of Nursing Students and Their Awareness of Patient Literacy Needs

Research has suggested that providers of health services must be aware of health literacy tools as elements of communication with patients. Poor health literacy is an epidemic that affects quality of care. The purpose of this study was to examine the functional health literacy of associate-degree nursing (ADN) students and their awareness of patients\u27 health literacy needs. This correlational study was designed to examine the relationship between the functional health literacy of ADN students and their awareness of their patients\u27 health literacy needs using the asset model and the health literate care model. A convenience sample of 131 ADN students in their last 2 semesters of nursing school completed the Test of Functional Health Literacy in Adults (TOFHLA) and the Knowledge and Skills Survey. Pearson correlation, linear regression, multivariate analysis of variance, and Spearman correlation were used to analyze the demographics of students, TOFHLA, and Knowledge and Skills Survey scores. The Pearson correlation indicated that the functional health literacy of ADN students and their awareness of the need to identify patients with low health literacy were statistically significant (p = .017). The results supported the need for improved training and support for students on the topic of health literacy along with opportunities for further research. The implication of social change directly relates the area of nursing education by further identifying associations between education and the application of health literacy, which leads to further discussion on organizational policy and curriculum changes. These types of analysis will lead to more patient-centered care and improved patient outcomes

Making mapping matter: a case study for short project international partnerships by global public health students

Background: A large number of global public health students seek international experience as part of their academic curriculum. These placements are often short, given the constraints of cost and time available within the academic calendar. In contrast to international electives for clinical students there are few published guidelines on practical, ethical or feasible projects. This paper describes a ten-day sanitation mapping project in Mumbai, India and explores the broader implications for global public health student electives. Methods: Three graduate public health students conducted a geographic review of sanitation facilities in Cheeta Camp informal settlement, Mumbai. Forty-six toilet blocks with 701 individual seats were identified. The project was reviewed ethically, educationally and logistically as a possible model for other short-term international projects. Conclusions: Clearer guidelines are needed to support non-clinical placements by global public health students. Projects that are feasible, relevant and meaningful should be foster maximise benefit for learners and host communities

Picture Detection in RSVP: Features or Identity?

A pictured object can be readily detected in a rapid serial visual presentation sequence when the target is specified by a superordinate category name such as animal or vehicle. Are category features the initial basis for detection, with identification of the specific object occurring in a second stage (Evans & Treisman, 2005), or is identification of the object the basis for detection? When 2 targets in the same superordinate category are presented successively (lag 1), only the identification-first hypothesis predicts lag 1 sparing of the second target. The results of 2 experiments with novel pictures and a wide range of categories supported the identification-first hypothesis and a transient-attention model of lag 1 sparing and the attentional blink (Wyble, Bowman, & Potter, 2009)National Institute of Mental Health (U.S.) (grant MH47432

Insecticide Resistance in the Bed Bug Comes with a Cost

Adaptation to new environmental stress is often associated with an alteration of one or more life history parameters. Insecticide resistant populations of insects often have reduced fitness relative to susceptible populations in insecticide free environments. Our previous work showed that three populations of bed bugs, Cimex lectularius L., evolved significantly increased levels of resistance to one product containing both β-cyfluthrin and imidacloprid insecticides with only one generation of selection, which gave us an opportunity to explore potential tradeoffs between life history parameters and resistance using susceptible and resistant strains of the same populations. Life history tables were compiled by collecting weekly data on mortality and fecundity of bugs from each strain and treatment throughout their lives. Selection led to a male-biased sex ratio, shortened oviposition period, and decreased life-time reproductive rate. Generation time was shortened by selection, a change that represents a benefit rather than a cost. Using these life history characteristics we calculated that there would be a 90% return to pre-selection levels of susceptibility within 2- 6.5 generations depending on strain. The significant fitness costs associated with resistance suggest that insecticide rotation or utilization of non-insecticidal control tactics could be part of an effective resistance management strategy
