GIS Collaborations in Saskatchewan: SGIC and the University of Saskatchewan Library (Accepted Manuscript version)
GIS (Geographic Information System) libraries face challenges at both ends of the spectrum when it comes to acquiring GIS data. On one hand, the increase in popularity of GIS driven by services like Google Earth, Bing maps, and open data has made large amounts of GIS data freely available to users. On the other hand, specialty GIS data products, often needed by researchers, industry, and government, can be so costly that they are impossible for a library to purchase on its own. In situations like the latter, collaborations often provide the solution for acquiring the necessary GIS data. This report discusses one of the most significant collaborations the University of Saskatchewan GIS Library has been involved with, the Saskatchewan Geospatial Imagery Collaborative (SGIC). The report will outline the collaboration, its goals and outcomes, as well as provide examples of how various members of the collaboration are utilizing the data. Lessons learned through this collaboration are also discussed, which can aid other libraries interested in collaborating to purchase special types of data
The Professional Development and Coaching of School Teachers: Real-Time Feedback
Teachers face many problems which directly impact student achievement. Some of these problems include lack of resources, high teacher attrition, and an overwhelming ratio of below grade level students. This study examines in-the-moment feedback as a form of professional development and coaching. The study seeks to understand if teachers deem this form of coaching and development as beneficial and high leverage in regard to positively affecting student achievement. Exploratory case study was used as the research design for this study. The population of this study was school teachers in urban school settings. The sample population entailed 11 school teachers currently working at an urban charter school district. An inductive analysis approach was employed using the nine steps of inductive analysis as identified and described by Hatch (2002). The findings revealed that, according to teachers, real-time feedback may positively impact student achievement when considering ten key tenets as outlined in this paper. Implications of this study suggest that real-time coaching and feedback—when received and implemented effectively—can and should be used to improve teachers’ instructional practices and have a positive impact on student outcomes. It is also implied that a shift in practice by teachers and leaders away from traditional coaching and feedback, to real-time coaching, could improve possibly improve teacher practices and student outcomes noticeably faster
The Effects of a Goal-Setting Program on Cognitive and Somatic State Anxiety, State Self-Confidence, and Performance of High School Swimmers
The purpose of this study was to determine the effects of a staggered approach, season long goal-setting training program on the state self-confidence, cognitive anxiety, somatic anxiety, and performance of high school female swimmers. It was hypothesized that the use of a goal-setting training program would result in the swimmers having higher state self-confidence, lower cognitive state anxiety, lower somatic state anxiety, and improved performance. Results indicated that participation in a ten week goal-setting training program successfully helped high school female swimmers achieve higher state self- confidence, lower cognitive state anxiety, lower somatic state anxiety, and improved performance
A Wavelet Collocation Method for some Fractional Models
This article presents an effective numerical approach based on the operational matrix of fractional order integration of Haar wavelets for dealing with the fractional models of the mixing and the Newton law of cooling problems. A general procedure of obtaining the fractional integration operational matrix of Haar wavelets which converts the fractional models into a system of algebraic equations is derived so that the computation is very simple and it is much effective than the conventional numerical methods. The reliability and the applicability of the current numerical technique for fractional models are examined by comparing the achieved results with the precise solutions
What predicts the actions taken toward observed child neglect?:the influence of community context and bystander characteristics
Objective: Using data from a sample of 3,679 respondents in 50 rural and urban communities in a midwestern state, the authors explore the relationship between individual and community characteristics and the provision of helping behavior when child neglect is observed. Method: Telephone surveys of community residents were analyzed in a series of logistic regression models. Results: At the individual level, age, gender, place of residence, and sentinel status were all found to have a significant effect. The level of role overlap, cohesion, comfort, and belongingness perceived to exist in the community were found to be important community-level predictors. Conclusion: Individual and contextual characteristics affected observation of a case of child neglect and the action taken
Impaired fertility and perceived difficulties conceiving in Ghana:measurement problems and prospects
What is the most appropriate measure of impaired fertility for understanding its social consequences in sub-Saharan Africa? The dearth of subjective measures in surveys in the region has prevented comparisons of subjective and objective measures. Perceived difficulties conceiving may have a greater impact than objective measures for social outcomes such as divorce, stigmatization and distress. This study compares 12- (clinical) and 24- (epidemiological) month measures from biomedicine and 5- and 7-year measures from demography with a subjective measure of impaired fertility using correlations, random effects models and test-retest models to assess relationships between measures, their association with sociodemographic characteristics and the stability of measures across time. Secondary panel data (1998-2004) from 1350 Ghanaian women aged 15-49 of all marital statuses are used. Longer waiting times to identification of impaired fertility required by demographic measures result in more stable measures, but perceived difficulties conceiving are most closely aligned with clinical infertility (r=0.61; p<0.05). Epidemiological infertility is also closely aligned with the subjective measure. A large proportion of those identified as having impaired fertility based purely on waiting times are successful contraceptors. Where subjective measures are not available, epidemiological (24-month) measures may be most appropriate for studies of the social consequences of impaired fertility. Accounting for contraceptive use is important in order to avoid false positives. Future research should consider a variety of measures of perceived difficulties conceiving and self-identified infertility to assess which is most valid; in order to accomplish this, it is imperative that subjective measures of infertility be included in social surveys in sub-Saharan Africa
