Membrane-integrated microfluidic device for high-resolution live cell imaging     

Epshteyn AA  Maher S  Taylor AJ  Holton AB  Borenstein JT  Cuiffi JD 《Biomicrofluidics》2011,5(4):46501-465016

The design and fabrication of a membrane-integrated microfluidic cell culture device (five layers,≤500 μm total thickness) developed for high resolution microscopy is reported here. The multi-layer device was constructed to enable membrane separated cell culture for tissue mimetic in vitro model applications and pharmacodynamic evaluation studies. The microdevice was developed via a unique combination of low profile fluidic interconnect design, substrate transfer methodology, and wet silane bonding. To demonstrate the unique high resolution imaging capability of this device, we used oil immersion microscopy to image stained nuclei and mitochondria in primary hepatocytes adhered to the incorporated membrane  相似文献   

Antecedents of perceived coach autonomy supportive and controlling behaviors: coach psychological need satisfaction and well-being     

Stebbings J  Taylor IM  Spray CM 《运动与训练心理学杂志》2011,33(2):255-272

Within the self-determination theory (Deci & Ryan, 2000) framework, research has considered the consequences of coaches' autonomy supportive and controlling behaviors on various athlete outcomes (e.g., motivation and performance). The antecedents of such behaviors, however, have received little attention. Coaches (N = 443) from a variety of sports and competitive levels completed a self-report questionnaire to assess their psychological need satisfaction, well-being and perceived interpersonal behaviors toward their athletes. Structural equation modeling demonstrated that coaches' competence and autonomy need satisfaction positively predicted their levels of psychological well-being, as indexed by positive affect and subjective vitality. In turn, coaches' psychological well-being positively predicted their perceived autonomy support toward their athletes, and negatively predicted their perceived controlling behaviors. Overall, the results highlight the importance of coaching contexts that facilitate coaches' psychological need satisfaction and well-being, thereby increasing the likelihood of adaptive coach interpersonal behavior toward athletes.  相似文献   

“I Managed It Pretty Good”: Birth Narratives of Adolescent Mothers     

Tracy R. Nichols  Margaret Brown  Sheryl L. Coley  Allyson Kelley  Kelly Mauceri 《The Journal of perinatal education》2014,23(2):79-88

The aim of this study was to understand adolescent mothers’ childbirth experiences. Semistructured interviews were conducted with participants recruited from a community-based program for adolescent mothers. Fourteen mothers described their birth experiences. Using a narrative analytic approach, responses were reconstructed into birth stories. Stories, condensed into poetic form, were compared and contrasted. Four unique categories emerged: connected births, surreal births, disconnected births, and disempowered births. Categories differed by agency, support, and emotional tone. Positive support was found in stories that portrayed high agency and positive affect, whereas problematic support was apparent in stories that conveyed passivity, frustration, and disappointment. This study has implications for tailoring childbirth education for adolescent mothers and can inform health-care professionals working with this population.  相似文献   

Morningness–Eveningness and College Advising: A Road to Student Success?     

Beverly Brown Schulke  Laura K. Zimmermann 《Mind, Brain, and Education》2014,8(4):227-230

In addressing the challenges faced by E‐type (evening‐type) students, researchers have pointed to the need for school schedules that reflect chronotypic concerns and the recognition of the importance of sleep for academic achievement and well‐being. One approach to dealing with this issue for adolescent students has been to move the start of the school day later. In college, however, schedules become more varied and the social context in which these challenges occur differs requiring more individualized approaches to scheduling. In spite of this, morningness–eveningness is rarely considered by college administrators, advisors, or individuals involved in student services. It is important that faculty and staff who work with students be aware of chronotypical influences on classroom performance and other aspects of student life so that they can help them succeed in college and beyond.  相似文献   

An Experimental Evaluation of Guided Reading and Explicit Interventions for Primary-Grade Students At-Risk for Reading Difficulties

Abstract

Considerable research evidence supports the provision of explicit instruction for students at risk for reading difficulties; however, one of the most widely implemented approaches to early reading instruction is Guided Reading (GR; Fountas & Pinnel, 1996), which deemphasizes explicit instruction and practice of reading skills in favor of extended time reading text. This study evaluated the two approaches in the context of supplemental intervention for at-risk readers at the end of Grade 1. Students (n = 218) were randomly assigned to receive GR intervention, explicit intervention (EX), or typical school instruction (TSI). Both intervention groups performed significantly better than TSI on untimed word identification. Significant effects favored EX over TSI on phonemic decoding and one measure of comprehension. Outcomes for the intervention groups did not differ significantly from each other; however, an analysis of the added value of providing each intervention relative to expected growth with typical instruction indicated that EX is more likely to substantially accelerate student progress in phonemic decoding, text reading fluency, and reading comprehension than GR. Implications for selection of Tier 2 interventions within a response-to-intervention format are discussed.  相似文献

Model Licenses and License Templates: Present and Future     

Liane Taylor  Eugenia Beh 《期刊图书馆员》2014,66(1-4):92-95

This presentation reviewed the standard model licenses that are available, including models such as LicensingModels.org and LibLicense, plus institution-specific licenses available online. The licenses’ strengths and weaknesses as templates were discussed. Best practices for creating a license template at one’s own institution were modeled, with standard language that one can use in negotiation. Problems and gaps in model licenses were raised, including formats or kinds of purchases that require new language that has not yet been standardized (such as e-books and streaming media). Suggestions for developing a new model license through community action were discussed.  相似文献   

An Experimental Test of Medical Disclosure and Consent Documentation: Assessing Patient Comprehension,Self-Efficacy,and Uncertainty     

Erin E. Donovan  Brittani Crook  Laura E. Brown  Angie E. Pastorek  Camille A. Hall  Michael S. Mackert 《Communication monographs》2014,81(2):239-260

Effectively conveying risks and hazards in medical disclosure and informed consent documentation is a crucial type of communication. However, existing protocols typically do not meet the needs of patients or practitioners. In the present study, we advance a reconceptualization of obtaining written informed consent by analyzing it as a process of uncertainty management rather than a matter of document readability and recall. Results of this randomized trial indicated that patients who reviewed a simplified consent document reported greater comprehension of medico-legal terminology and lower uncertainty about the document, although they did not evince greater self-efficacy. Health literacy was a significant moderator of the relationship between consent form version and comprehension.  相似文献   

Authors and electronic publishing: what authors want from the new technology     

Alma Swan  Sheridan Brown 《Learned Publishing》2003,16(1):28-33

Responses from almost 1,250 academic authors around the world were analysed to obtain their views on electronic publishing of learned journals. Currently, having a print version of journals is still more important to them than an electronic version. The issue of greatest importance to authors and readers is the continuing availability of back volumes, and there are strong concerns about pricing of electronic journals. The potential gains in publication speed through publishing electronically appear not to be a priority. Electronic preprint and reprint archives are used very little at present, with the exception of the physics and mathematics communities. Of all publisher‐mediated tasks, the peer‐review process is the most valued, followed by provision of citation‐linking. Respondents' views of future developments in electronic publishing are also explored.  相似文献
