This paper identifies salient practices of faculty mentors of undergraduate research (UR) as indicated in the extensive literature of the past two decades on UR. The well-established benefits for students involved in UR are dependent, first and foremost, on high-quality mentoring. Mentorship is a defining feature of UR. As more and different types of colleges and universities strive to meet student demand for authentic scholarly experiences, it is imperative to identify what effective UR mentors do in order to ensure student engagement, quality enhancement, retention, and degree-completion. We offer an original analysis of the literature on UR mentoring in which we identify 10 significant “lessons learned,” or evidence-based practices of effective UR mentors that apply broadly across disciplines, students, institutions, and mentoring approaches. 相似文献

The emerging technologies on mobile-based diagnosis and bioanalytical detection have enabled powerful laboratory assays such as enzyme-linked immunosorbent assay (ELISA) to be conducted in field-use lab-on-a-chip devices. In this paper, we present a low-cost universal serial bus (USB)-interfaced mobile platform to perform microfluidic ELISA operations in detecting the presence and concentrations of BDE-47 (2,2′,4,4′-tetrabromodiphenyl ether), an environmental contaminant found in our food supply with adverse health impact. Our point-of-care diagnostic device utilizes flexible interdigitated carbon black electrodes to convert electric current into a microfluidic pump via gas bubble expansion during electrolytic reaction. The micropump receives power from a mobile phone and transports BDE-47 analytes through the microfluidic device conducting competitive ELISA. Using variable domain of heavy chain antibodies (commonly referred to as single domain antibodies or Nanobodies), the proposed device is sensitive for a BDE-47 concentration range of 10−3–104 μg/l, with a comparable performance to that uses a standard competitive ELISA protocol. It is anticipated that the potential impact in mobile detection of health and environmental contaminants will prove beneficial to our community and low-resource environments. 相似文献

The purpose of this qualitative study was to examine teachers’ attitudes and experiences with coaching. This study was conducted in advance of a planned randomized controlled trial of a coaching intervention to better align the model with teachers’ needs and goals. Thirty-four K–5 general (n = 26), special education (n = 6), and educational support staff (n = 2) working in two high-poverty schools participated in focus groups. Interrater reliability between independent coders was high (К = 0.92; range: 0.76–1.0). Thematic analyses identified facilitators and barriers to teacher participation in the planned intervention and were used to improve upon the existing coaching model. Themes focused on advantages and disadvantages to coaching and characteristics of effective coaches and coaching models. Implications of findings for research and practice are discussed. 相似文献

Neighborhood schools engender the idea that schools can be integral community centers, with learning facilitated by the personal relationships developed among teachers, administrators, students, and parents. Neighborhood schools also have represented stigmatized segregated spaces located in communities with high poverty rates, low high school graduation rates, and little opportunity for social mobility. Drawing from print and online media sources related to the closure and reopening of D.C. Virgo Middle School (Virgo), a racially- and economically-segregated middle school in an urban, southern community, this study uses conceptual content analysis to examine the competing discourses surrounding Virgo. The authors conclude that the public discourse examined herein represents the tension between public schools as stigmatizing beloved spaces. As a stigmatizing space, the school can transfer the stigmatized identity to associated students and personnel. As a beloved space, the school can nurture possibility and hope. 相似文献

Purpose:
A systematic literature review was conducted to synthesize what is known about informationists, highlight program models, and suggest areas for future research.Methods:
Articles retrieved through database searching were reviewed for relevance. Informationist case reports were identified and coded according to an attributes checklist. Data from other retained publications were synthesized under broad themes. The few research studies found were reviewed for level of evidence.Results:
Of 113 papers reviewed, the study identified 7 classic and 8 emerging informationist programs. Two major models are apparent, clinical and research, with priorities differing according to program maturity. The literature synthesis also brought together current thinking about informationist qualifications; practice roles; setting characteristics; education and training; organizational, programmatic, and service provider success factors; and challenges and barriers. Program outcomes to date are reported, and future research topics suggested. Specific findings will assist informationist program planners.Conclusions:
While the informationist concept remains in the early adopter stage, it appears that domain knowledge, continuous learning, and embedding (working in context) are essential to success. The need for librarians to transition to greater specialization and libraries to emphasize customized service was underscored. A research agenda focused on information management, dissemination, behaviors, and economics is proposed.Highlights
- After years of emphasizing the generalist librarian, health sciences librarians must become more specialized, paralleling the health care environment in which they work.
- An embedded informationist is more likely to achieve credibility, acceptance, and sustainability than an impersonal information service provided at a distance.
- Subject expertise is essential for the informationist.
- Model informationist programs with the greatest stability are library funded.
- Because informationist programs are inherently targeted to small groups, multisite studies are necessary to achieve robust evaluation.
Implications
- A library starting an informationist program should review existing models, identify local needs, set program objectives, and then select the most appropriate approaches for its users.
- Programmatic emphasis should be placed on both technical and service excellence.
- Organizational commitment is needed for knowledge integration into practice and for the informationists'' lifelong learning.

Linked lives: stability and change in maternal circumstances and trajectories of antisocial behavior in children 总被引：1，自引：0，他引：1
Drawing on the notion of linked lives, this study examined the effects of stability and change in maternal circumstance on developmental trajectories of antisocial behavior in children 4 to 7 years of age. Using data from a national sample of young mothers and growth curve analysis, the study demonstrated that early maternal circumstances influences early antisocial behavior, whereas stability and change in these circumstances both exacerbate and ameliorate behavior problems. Of particular note, meaningful escape from poverty attenuates antisocial behavior whereas persistence in poverty or long-term movement into poverty intensifies such problems. These findings highlight the importance of structural context for parenting practices and the need to consider child development in light of dynamic and changing life-course fortunes of parents. 相似文献

This paper identifies a process, developed in recent research, to provide curriculum leaders and policy-makers with a practical and flexible approach for designing and implementing curriculum. It is a changed way for bringing about change. Founded on sound principles of curriculum theorizing, it refines existing curriculum theory in higher education contexts and contributes to the ever-growing body of understanding on curriculum decision-making. A thorough investigation of the engineering education context, including the analysis of an engineering case study, was carried out to identify issues that impinge on curriculum decision-making, including the consideration of professional engineering needs, the social and economic pressures, institutional parameters and student factors. As no such systematic process currently existed for this context, the investigation also considered the curriculum and pedagogical theories that underpin the strategic and operational nature of bringing about curriculum change. The process represents a significant breakthrough in higher education faculties. It directs policy-makers to consider parameters in addition to those traditionally addressed. It recommends a holistic view of curriculum and suggests that there are explicit ramifications for the policies in faculties that govern how curriculum change takes place. 相似文献
