Ecological Mural as Community Reconnection

Murals are particularly visually captivating forms of public art due to their size and accessibility. Mural images also capture public attention and provoke viewers to explore layers of meaning and find hidden stories. They are often in places that people come to visit, study, play, congregate and discuss matters that may relate to the content of the mural. To this end, murals can be effective tools for helping communities think about their environmental issues. This article discusses the Mystic River mural project in Somerville, Massachusetts, USA. It addresses how the local art councils, mural artists, local students, community members and non‐profit organisations collaborated to carry out this ongoing mural project. The purpose of this research is to examine how Mystic River eco‐murals were created, what challenges and benefits the eco‐murals provided, how local social concerns were represented through the eco‐murals, how eco‐murals can continue to promote environmental awareness and inspire youth about their community and the local environment, and how the mural can continue to reflect or affect the meaning of the place. This process can serve as an example for other communities that seek to address their environmental concerns through public art.     

The Effects of a Kit-Based Science Curriculum and Intensive Science Professional Development on Elementary Student Science Achievement

The science achievement of 226 5th graders from districts that have a kit-based inquiry science curriculum supported by intensive professional development (PD) is compared with data from a group of 173 5th graders from other districts that use nonkit science materials and do not have systematic science PD for teachers. Within the kit-based project, the sample of project teachers is stratified to select teachers with a high number of science PD hours versus those with few hours. While there were no significant differences in the mean total scores for kit-based students with low PD versus high PD teachers, the kit-based classrooms scored significantly higher than students in nonkit classrooms on both the pretest and posttest, though there were significantly more minutes of science instruction in the nonkit classrooms. Finally, nonkit teachers taught more units of shorter length and reported lower levels of preparedness to use reform pedagogical approaches.     

The Impact of an SES-Based Model on a College's Undergraduate Admissions Outcomes

In Grutter vs. Bollinger, the U.S. Supreme Court ruled that the use of race as one factor, among many in admissions decisions is constitutional. It is not known, however, whether future legal opinions will continue to uphold the use of affirmative action policies. Some have argued that class-based preferences can achieve many of the same goals as in affirmative action while being more likely to withstand legal challenges. To date, no empirical studies have been conducted on the potential impact of a class-based admissions policy if implemented at an undergraduate institution. This paper reports on a study at a selective public college and compares a number of outcomes under three admissions models: the original admissions decisions, a purely academic model, and an socio-economic status (SES)-based model. The findings showed that use of the SES-based model would have led to a more academically qualified class than in the original admitted class while maintaining substantially greater student diversity that was found under the academic model. An admissions policy based on preferences for socio-economically disadvantaged applicants appears to hold promise for other colleges and universities with similar institutional and applicant characteristics. The ideas and research design reported in this paper are based on the doctoral dissertation study of the second author, Undergraduate Admissions Models Incorporating Socioeconomic Factors (Johnson, 2000).     

A success story: A large urban district offers a working model for implementing multisensory teaching into the resource and regular classroom

A large urban school district contracted with a private nonprofit educational foundation to train 126 special education resource teachers in the last three years in an Orton-Gillingham-based program. These teachers are currently teaching learning-disabled students in groups of 8–10 at the elementary level and 10–13 students at the secondary level. Learning-disabled students who qualify for Special Education, either in reading or spelling, or both, are receiving the instruction. The teachers took a Basic Introductory Class (90 hours of Advanced Academic Credit offered by the Texas Education Agency, or six hours of graduate credit at a local university) in order to teach the program in the resource setting. A two year Advanced Training included annual on-site observations, two half-day workshops each fall and spring, and a two-day advanced workshop in the second summer. First grade teachers, one selected from each of the 164 campuses, supervisors, and principals attended a 25-hour course on “Recognizing Dyslexia: Using Multisensory Teaching and Discovery Techniques.” The first grade teachers and special education resource teachers collaborated to provide inservice training for their colleagues. Research, conducted by the district’s Research Department, reveals statistically significant gains in reading and spelling ability for the learning-disabled resource students as measured by the Woodcock Reading Mastery Test-Revised, and the Test of Written Spelling.     

Effects of identical context on visual pattern recognition by pigeons

The effects of identical context on pattern recognition by pigeons for outline drawings of faces were investigated by training pigeons to identify (Experiment 1) and categorize (Experiment 2) these stimuli according to the orientation of the mouth—an upright U shape representing a smiling mouth or an inverted U shape representing a sad mouth. These target stimuli were presented alone (Pair 1), with three dots in a triangular orientation to represent a nose and eyes (Pair 2), and with the face pattern surrounded by an oval (Pair 3). In Experiment 1, the pigeons trained with Pair 1 were most accurate, those trained with Pair 2 were less so, and those trained with Pair 3 failed to acquire the discrimination within eighty 100-trial sessions. The same ordering was found in Experiment 2 for pigeons trained on the three pairs simultaneously. The authors suggest that a contrasting finding in humans, the face superiority effect, might be due to a gain in discriminability resulting from recognition of the pattern as a face. An exemplar model of information processing that excludes linguistic coding accounts for the present results.     

Optimization of some factors affecting the performance of query expansion

This paper examines the factors affecting the performance of global query expansion based on term co-occurrence data and suggests a way to maximize the retrieval effectiveness. Major parameters to be optimized through experiments are term similarity measure and the weighting scheme of additional terms. The evaluation of four similarity measures tested in query expansion reveal that mutual information and Yule's Y, which emphasize low frequency terms, achieve better performance than cosine and Jaccard coefficients that have the reverse tendency. In the evaluation of three weighting schemes, similarity weight performs well only with short queries, whereas fixed weights of approximately 0.5 and similarity rank weights were effective with queries of any length. Furthermore, the optimal similarity rank weight achieving the best overall performance seems to be the least affected by test collections and the number of additional terms. For the efficiency of retrieval, the number of additional terms needs not exceed 70 in our test collections, but the optimal number may vary according to the characteristics of the similarity measure employed.     

Using A Split-ballot Survey to Explore the Robustness of the 'MIP' Question in Agenda-Setting Research: A Methodological Study

Three aspects of the ‘most important problem’ questionused in agenda-setting research to measure issue salience amongthe public were examined. A split-ballot design in a state-widesurvey compared versions of the public agenda with a socialframe of reference versus a personal frame of reference, versionsusing the traditional term ‘problem’ versus ‘issue’,and the effects of question order. High correlations betweenthe different versions were found in all three sets of comparisons.     

Leveraging microgrants to support capacity-building workshops in low- and middle-income countries for meeting the Sustainable Development Goals

Twenty fifteen marked the year of assessment for the Millennium Development Goals (MDGs). The MDGs that achieved the greatest success were those where evidence-based practice (EBP) interventions were implemented. The ability to practice evidence-based medicine is grounded in the creation of and access to medical literature that synthesizes research findings. The role that global health literature played in the success of the MDGs demonstrates that medical libraries and librarians have a role to play in achieving the Sustainable Development Goals (SDGs).Librarians can hold capacity-building workshops that provide instruction on how to access evidence-based literature and also train health professionals to conduct synthesis research. Research findings conducted by in-country health professionals are more likely to address issues being faced by local communities and will afford the possibility of obtaining the necessary evidence-based answers that can then be used to implement policies to resolve public health issues identified in the SDGs.This paper discusses how an international team of librarians leveraged funding from a Medical Library Association/Librarians without Borders/Elsevier Foundation/Research4Life grant to hold a capacity-building workshop in Zimbabwe and follow-up online trainings. The workshop focused on accessing evidence-based resources and conducting synthesis research. Outcomes included the creation and policy implementation of evidence-based knowledge products in alignment with local needs and galvanizing a multisectoral group of key individuals who have gone on to collaborate toward the vision of creating a Zimbabwe innovation hub. Looking ahead, such grants can be leveraged to conduct capacity-building to support knowledge translation and other local training needs.
