Get Ready,Get In,Get Through: Factors that Influence Latino College Student Success

“Get ready, get in, and get through.” Latino adolescents and young adults are enrolling in the nation’s colleges and universities at record numbers. However, completion rates of Latinos range from 8% to 25%. We examined individual rather than organizational factors shown to influence Latino student post-secondary levels of success. Influences include academic experience; demographic, personal, and family characteristics; and cultural factors. Four colleges that have specifically addressed success were selected to show how programs link individual factors with success. Implications for the findings are discussed.

Early-Childhood Poverty and Adult Attainment, Behavior, and Health

This article assesses the consequences of poverty between a child's prenatal year and 5th birthday for several adult achievement, health, and behavior outcomes, measured as late as age 37. Using data from the Panel Study of Income Dynamics (1,589) and controlling for economic conditions in middle childhood and adolescence, as well as demographic conditions at the time of the birth, findings indicate statistically significant and, in some cases, quantitatively large detrimental effects of early poverty on a number of attainment-related outcomes (adult earnings and work hours). Early-childhood poverty was not associated with such behavioral measures as out-of-wedlock childbearing and arrests. Most of the adult earnings effects appear to operate through early poverty's association with adult work hours.     

Teaching a Human Sexuality Course: What Are Counseling Students Thinking?

The pervasiveness of sexual issues in counseling suggests the necessity of educating counseling students about relevant topics. Students enrolled in a human sexuality course anonymously submitted topical questions and secrets/fantasies. Following a content analysis, findings depicted themes of content and tone that provided curricular implications for counselor educators.     

“You don’t have to travel the world”: accumulating experiences on the path toward globally competent teaching

As classrooms become increasingly diverse and students need more complex skills for collaboratively addressing transnational issues, we need a better understanding of the factors that contribute to globally competent teaching. Education research has highlighted the benefits of study abroad and overseas teaching, as well as local cross-cultural immersion, but these options are not always feasible. We sought to identify the various means by which teachers develop global competence. Through this qualitative case study of 10 global educators, we found that international travel, though present in some instances, was not always necessary. In fact, it was an accumulation of experiences that prompted teachers to incorporate global perspectives, lessons, and skill development throughout their careers. Thus, globally competent teaching may be better conceptualized as a path, rather than as an end goal.     

Mapping the core journals of the physical therapy literature

Objectives:

The purpose of this study was to identify (1) core journals in the literature of physical therapy, (2) currency of references cited in that literature, and (3) online databases providing the highest coverage rate of core journals.

Method:

Data for each cited reference in each article of four source journals for three years were recorded, including type of literature, year of publication, and journal title. The journal titles were ranked in descending order according to the frequency of citations and divided into three zones using Bradford''s Law of Scattering. Four databases were analyzed for coverage rates of articles published in the Zone 1 and Zone 2 journals in 2007.

Results:

Journal articles were the most frequently cited type of literature, with sixteen journals supplying one-third of the cited journal references. Physical Therapy was the most commonly cited title. There were more cited articles published from 2000 to 2007 than in any previous full decade. Of the databases analyzed, CINAHL provided the highest coverage rate for Zone 1 2007 publications.

Conclusions:

Results were similar to a previous study, except for changes in the order of Zone 1 journals. Results can help physical therapists and librarians determine important journals in this discipline.

Highlights

• More cited references were published in the last eight years studied than in any previous full decade.
• Physical Therapy, Archives of Physical Medicine and Rehabilitation (APMR), and Spine were the most frequently cited titles. Previous studies found APMR to be the most cited journal.
• CINAHL provided the highest coverage rate for the most commonly cited titles, with MEDLINE and EMBASE providing the best coverage for the next group of titles.

Implications

• Health sciences librarians and clinicians can use these results to identify important journals for developing collections and determining the need for access to back issues of journals.
• Multiple databases are needed for comprehensive coverage of the physical therapy discipline

Optofluidic characterization of marine algae using a microflow cytometer

The effects of global warming, pollution in river effluents, and changing ocean currents can be studied by characterizing variations in phytoplankton populations. We demonstrate the design and fabrication of a Microflow Cytometer for characterization of phytoplankton. Guided by chevron-shaped grooves on the top and bottom of a microfluidic channel, two symmetric sheath streams wrap around a central sample stream and hydrodynamically focus it in the center of the channel. The lasers are carefully chosen to provide excitation light close to the maximum absorbance wavelengths for the intrinsic fluorophores chlorophyll and phycoerythrin, and the excitation light is coupled to the flow cytometer through the use of an optical fiber. Fluorescence and light scatter are collected using two multimode optical fibers placed at 90-degree angles with respect to the excitation fiber. Light emerging from these collection fibers is directed through optical bandpass filters into photomultiplier tubes. The cytometer measured the optical and side scatter properties of Karenia b., Synechococcus sp., Pseudo-Nitzchia, and Alexandrium. The effect of the sheath-to-sample flow-rate ratio on the light scatter and fluorescence of these marine microorganisms was investigated. Reducing the sample flow rate from 200 μL/min to 10 μL/min produced a more tightly focused sample stream and less heterogeneous signals.
