This paper examines graduate research assistants' informal applied learning experiences on the evaluation team at a university-based agricultural safety and health research center. The case study aims to identify the specific learning outcomes derived from the experience, as described by students, and the factors that facilitated them. The research team used a semi-structured focus group tool, and the focus group participants conducted their own analysis and interpretation of the data.

This study used data from the National Longitudinal Transition Study 2012 (NLTS 2012) to explore the future goal aspirations of students with extensive support needs who participate in alternate assessments, compared to other students with extensive support needs and to students with other disabilities. We examined students' individualized education program (IEP)/transition planning meeting experiences and postschool goals in relation to their functional, communication, and self-advocacy skills, as well as their school/community support. Students with other disabilities held higher expectations than all students with extensive support needs for future participation in postsecondary education, employment, independent living, and financial independence.

After spinal cord injury (SCI), use chronic urinary catheters for bladder management is common, making these patients especially vulnerable to catheter-associated complications. Chronic catheterization is associated with bacterial colonization and frequent catheter-associated urinary tract infections (CAUTI). One determinant of infection success and treatment resistance is production of catheter-associated biofilms, composed of microorganisms and host- and microbial-derived components.

Existing scholarship indicates a wide range of variance and inconsistency in how evaluation is taught in introductory-level graduate courses between and across instructors and universities and within programs. The purpose of this study was to empirically explore faculty, student, and employers' perceptions of what should be included in a graduate level introductory course on program evaluation. The researchers used a mixed methods approach (survey and focus group) to build consensus on and articulate key elements of an introductory evaluation course, as well as the approximate amount of time that stakeholders feel should be invested in each topic area.

Research suggests that bullying victimization occurs at higher rates among students with autism spectrum disorder (ASD) than among their typically-developing peers. This study used data from the National Longitudinal Transition Study 2012 to explore differences in student and family characteristics between students with ASD and students with all other special education disability categories. The study also examined characteristics serve as predictors of bullying and victimization.

Aim: Lower urinary tract symptoms (LUTS) are a common urological referral, which sometimes can have a neurological basis in a patient with no formally diagnosed neurological disease ("occult neurology"). Early identification and specialist input is needed to avoid bad LUTS outcomes, and to initiate suitable neurological management.

Methods: The International Continence Society established a neurological working group to consider: Which neurological conditions may include LUTS as an early feature? What diagnostic evaluations should be undertaken in the LUTS clinic? A shortlist of conditions was drawn up by expert consensus and discussed at the annual congress of the International Neurourology Society.

Pedagogy and andragogy refer to the philosophical and empirical assumptions that instructors make about what and how people learn. These assumptions guide much of the subsequent instructional design process, including learning objectives, learning experiences, assessment techniques, and more. Most of the existing literature in evaluator education is descriptive in nature, and there has been limited attention to research on pedagogy specific to evaluation or identification of effective practices for teaching evaluation.

Education is critically important for the maintenance and growth of programme evaluation and its emergence as a profession. This position paper presents evaluator education as an initiative and provides a foundation for its evaluation. In it, the authors use Stufflebeam's Context, Input, Process, and Product (CIPP) model to frame a review of the literature and practice.

Background: Leg pain associated with walking is sometimes incorrectly attributed to hip osteoarthritis (OA) or lumbar spinal stenosis (LSS).

Purpose: This study compared physicians' values of signs and symptoms for diagnosing and differentiating hip OA and LSS to their clinical utility.

Study Design/setting: Musculoskeletal physicians were surveyed with online questionnaires.

Transfusion-related acute lung injury (TRALI) is a rare complication of transfusion, for which the true incidence remains obscure, since there are a number of factors that may lead to misdiagnosis. Despite this, it continues to be the leading cause of transfusion-associated mortality. Here we present a historical case of TRALI in an elderly female who received group AB plasma and discuss how current mitigation strategies would likely have prevented its occurrence.

Aims: To compare urodynamic parameters in two groups of older women who have overactive bladder (OAB) symptoms: those with normal and those with elevated post-void residual (PVR).

Methods: Secondary data analyses were conducted on medical record data from 203 women who were 65 years or older and who completed urodynamic testing. Of these, 151 (74%) medical records met the study criteria.

Introduction: The neurogenic urinary bladder has been known for at least 30 years now and the concepts behind it are continuously evolving, but there is actually not much work that has been done to accumulate solid clinical evidence in this field. We review the surgical and experimental techniques used in the management of this condition.

Material And Methods: TO ACHIEVE OUR GOAL, WE PERFORMED INTERNET SEARCHES USING THE SAME SEARCH STRING: Urinary bladder, neurogenic.

Introduction: The neurogenic urinary bladder is defined as a dysfunctional bladder associated with a known neurological injury. We review the data from good quality clinical trials looking at drug therapy for the neurogenic bladder.

Materials And Methods: IN ORDER TO IDENTIFY AS MANY PROSPECTIVE TRIALS AS POSSIBLE, WE PERFORMED INTERNET SEARCHES, USING THE SAME SEARCH STRING: Urinary Bladder, neurogenic (MESH).

Pregnant women experience extensive physiologic and structural changes during pregnancy that affect their daily functioning. The addition of osteopathic manipulative treatment (OMT) to the standard care of pregnant women has been hypothesized to enhance homeostasis and improve quality of life as the body adapts to these changes. Specifically, it has been postulated that OMT can ease pain in pregnant women by eliminating somatic dysfunction and maintaining proper structure.

Beam shaping using Gaussian beam modes.

J Opt Soc Am A Opt Image Sci Vis

February 2010

A beam shaping method is presented where a diffractive optical element (DOE) is designed by optimizing the complex mode coefficient weights of a set of Gaussian beam modes. This method is compared with the more standard unidirectional approach. Differential evolution is used for the optimization in both the unidirectional and Gaussian beam mode optimization methods.

Drop foot arises from dysfunction within the anatomic, muscular, or neurologic aspects of the lower extremity. The authors describe a patient with drop foot who had a compressed common peroneal nerve caused by posterior fibular head dysfunction. One 15-minute session of osteopathic manipulative treatment resolved the patient's symptoms.
