Using Metaphors to Aid Student Meta-Learning: When You’re Learning at Your Best Your Like What?  [PDF]
Sarah Nixon
Creative Education (CE) , 2013, DOI: 10.4236/ce.2013.47A2006

Metaphors are widely discussed within educational research and this paper adds to the body of knowledge in relation to students using these as a tool to support meta-learning. Metaphors free up space for creative thinking by moving the mind from one place to another and have been found to be an effective cognitive device for learning. This project focuses on what students are like when they are “learning at their best” and discusses what knowing this information does for both individual self-awareness and working with others. Six final year students spent half a day exploring, developing and pictorially representing their “learning at best” metaphors. All six metaphors were different and showed the internal representations of the individuals when they were learning at their best. However out of the discourse common themes arose from the group in relation to what was needed to support learning these included time of day, mood, pace and environment. All six students were positive that the development of personal learning metaphors was beneficial and thought that it was important that these were developed systematically over time. The benefits were highlighted to be both for the individual working on their own and for understanding others in group work situations.

A Day in the Life of an Early Childhood Teacher: Identifying the Confronting Issues and Challenges That Arise  [PDF]
Sarah Ohi
Creative Education (CE) , 2014, DOI: 10.4236/ce.2014.511115

Recent emphasis upon Early Childhood as an educational priority for the Australian Government has resulted in increases in funding, government initiatives, course providers and the introduction of new policies to the sector in order to improve the quality of early childhood education. The study reported here investigated the “reality” of what it means to be an Early Childhood Teacher within this changing context and identified the roles and responsibilities and the associated challenges. A case study involving observation and interviews with five Bachelor qualified Teachers from varied early childhood settings was undertaken in order to gain knowledge about their experiences and perspectives on their work. The data were analyzed using a grounded theory approach involving the identification of key themes and issues about the nature of teachers’ work. The findings revealed that in their everyday practice teachers played a complex array of roles that required them to contribute far more than just their teaching skills and knowledge. They were expected to concurrently enact the roles of educator, leader, advocate, communicator, counsellor and administrator whilst juggling everyday challenges including a “lack of time”, the need for “further support and more resources” and “building successful partnerships with parents”.

Behavioural Sleep Disorders across the Developmental Age Span: An Overview of Causes, Consequences and Treatment Modalities  [PDF]
Sarah Lee Blunden
Psychology (PSYCH) , 2012, DOI: 10.4236/psych.2012.33035
Abstract: Behavioural sleep problems, that is, sleep problems that do not have a physiological aetiology, but rather a behavioural or psychological aetiology, are reported in between 20% - 40% of children and adolescents. These sleep disorders are categorised as Behavioural Insomnia of Childhood (BIC) in the International Classification of Sleep Disorders. BIC can result in short sleep duration and poor quality sleep and can have wide ranging effects on mental and physical health, cognitive and social functioning and development in infants, pre-schoolers, school aged children and adolescents. Each age group have a particular set of behaviourally based sleep disorders. This paper presents a broad overview of BIC and covers essential information about these sleep disorders, their aetiologies, effects on development and non medical treatment modalities.
Performance Study of a Distributed Web Server: An Analytical Approach  [PDF]
Sarah Tasneem, Reda Ammar
Journal of Software Engineering and Applications (JSEA) , 2012, DOI: 10.4236/jsea.2012.511099
Abstract: With the rapid expansion of the Internet, Web servers have played a major role in accessing the enormous mass of Web pages to find the information needed by the user. Despite the exponential growth of the WWW, a very negligible amount of research has been conducted in Web server performance analysis with a view to improve the time a Web server takes to connect, receive, and analyze a request sent by the client and then sending the answer back to client. In this paper, we propose a multi-layer analytical approach to study the web server performance. A simple client-server model is used to represent the WWW server in order to demonstrate how to apply the proposed approach. We developed a systematic, analytical methodology to quantify the communication delay and queuing overhead in a distributed web server system. The approach uses the Computation Structure Model to derive server processing time required to process a request sent from a client and queueing model to analyze the communication between the clients and the server.
Preferences for behavioral therapies for chronic insomnia  [PDF]
Sarah Ibrahim, Souraya Sidani
Health (Health) , 2013, DOI: 10.4236/health.2013.511240
Abstract: Purpose: The purpose of this study was twofold: to examine the acceptability and preference for the two behavioral therapies, and to identify factors persons with chronic insomnia take into account when choosing treatment. Methods: The data were obtained in a large trial evaluating the effects of Stimulus Control and Sleep Restriction therapies. Prior to treatment, participants completed the treatment acceptability and preference (TAP) questionnaire, which described the Stimulus Control Therapy and the Sleep Restriction Therapy and requested participants to rate the acceptability of each treatment option before choosing one for the management of chronic insomnia. Open-ended questions were used to explore the factors that participants considered when making a choice. Results: Participants rated the Sleep Restriction Therapy as acceptable and 70.2% of participants preferred it over Stimulus Control Therapy. The factors that influenced participants’ choice related to the familiarity, previous personal experience, novelty, and suitability of the treatment. Conclusion: Persons have expressed a preference for treatments to manage chronic insomnia. Healthcare providers are in a position to provide relevant information about treatment options in order to help persons make informed treatment related decisions.
Fermented Milk Products from Different Milk Types  [PDF]
Olusola Ladokun, Sarah Oni
Food and Nutrition Sciences (FNS) , 2014, DOI: 10.4236/fns.2014.513133
Abstract: Yogurt was produced from milk obtained from cow milk, goat milk, soymilk and coconut milk by fermentation using starter cultures of Lactobacillus bulgaricus and Lactobacillus acidophilus.The results obtained showed that the initial pH of the fresh milk samples were slightly acidic: cow milk (6.3), goat milk (6.2), soymilk (6.4) and coconut milk (6.0). The pH results of the various fermented milk at 0 hour of production were goat milk (5.24), cow milk (5.85), soymilk (5.73) and coconut milk (5.98), but at 72 hours, all the milk samples tended to be more acidic due to the fermentation and had lower pH values. All the fresh milk samples had the high moisture content which ranged from 63.34% - 76.90%. Fat content ranged between 9.76% - 15.02%. Crude protein ranged from 7.17% - 32.17% with goat milk having the highest protein level of (32.17%). Ash content had the range of 0.52% - 0.96%. Goat milk had the highest ash content value and coconut milk had the least value. Specific gravities of soymilk, goat milk, cow milk and coconut milk were 1.018, 1.030, 1.016 and 1.01 g/ml respectively. Taste, color, mouth feel and odor were acceptable at 0 hours of production but their value depreciated with storage at room temperature. This study was able to establish the close nutritional gap between cow milk, goat milk, soya and coconut milk yoghurt preparations. The nutritional values obtained from the proximate analysis of the milk samples were comparable. This clearly points to the fact that either of the food can substitute for each other based on the values established from this study.
Effect of Bisphosphonate on Osteoclast of Bone  [PDF]
Sarah Ralte, Asima Bhattacharyya
Forensic Medicine and Anatomy Research (FMAR) , 2014, DOI: 10.4236/fmar.2014.23011
Abstract: Bisphosphonates are synthetic analogues of naturally occurring pyrophosphate molecule and are potent inhibitors of osteoclastic bone resorption. Bisphosphonates bind to hydroxyapatite crystals with high affinity and after incorporation by osteoclasts, the primary target cell, it inhibits osteoclastic bone resorption. The anti-resorptive effect has been shown to occur in organ culture as well as in-vivo, but the precise mechanism by which it exerts its bone resorbing effect is not yet fully understood. In vitro and in vivo studies have demonstrated that zoledronate is a more potent inhibitor of osteoclasts than earlier bisphosphonates. Bisphosphonates have now emerged as a leading therapeutic agent for the treatment of hypercalcaemia of malignancy, bone metabolic diseases, Paget’s disease and postmenopausal osteoporosis.
An Empirical Review of Library Discovery Tools  [PDF]
Xi Shi, Sarah Levy
Journal of Service Science and Management (JSSM) , 2015, DOI: 10.4236/jssm.2015.85073
Abstract: The Internet search concept has fostered an expectation that all users need to do is to feed relevant terms to a search engine to describe a topic or to ask a question, and click “search”. The search engine is then expected to return a list of possible relevant and useful results for users to choose from. Based on this search concept, library system developers have been developing and constructing software programs for library databases that manage scholarly information. These software programs are known as library discovery tools, or web-scale discovery (WSD) tools. In this article, the term “library discovery tools” is used when discussing search engines designed for the libraries, WSD is included. Library discovery tools are intended for intelligent searches for educational or research purposes. This article provides a practical analysis of available library discovery tools in context of the present-day explosion of available open search engines on the Internet. The focuses of our analysis include how discovery tools are expected to manage library collections, provide access to scholarly information content, as well as other factors, such as budgetary considerations, when choosing or adding a discovery tool for a library.
Fidelity of Intervention Implementation: A Review of Instruments  [PDF]
Sarah Ibrahim, Souraya Sidani
Health (Health) , 2015, DOI: 10.4236/health.2015.712183
Abstract: Background: Interventions, whether simple or complex, are increasing in health care in response to the growing complexity and acuity of patient’s conditions. Monitoring the fidelity of implementing interventions is challenging. A common method to assess and monitor fidelity of intervention implementation is through a structured, reliable and valid instrument. Purpose: The purpose of this paper is to examine existing instruments measuring fidelity of intervention implementation in order to determine aspects of fidelity that have been assessed and reported on the reliability and validity of these instruments. Design: A descriptive review was conducted. Studies were included if they described and reported on the fidelity of intervention implementation instruments, their psychometric properties were published between 1980 and 2015. Methods: Data were extracted on the study characteristics, levels and aspects of fidelity and the psychometric properties, specifically the reliability and validity of the fidelity of intervention implementation instruments. Results: In total, 21 studies were included in the review. Overall results showed that some aspects and levels of fidelity of intervention implementation are included in the instruments. At the theoretical level, fidelity of intervention implementation is not accounted for majority of the studies and few explicitly reports on the use of instruments to evaluate intervention differentiation. At the operational level, interventionists’ adherence and competence are included in the instruments; however, participants’ engagement, exposure and enactment are not. The instruments demonstrate acceptable level of validity and reliability. Conclusion: Sustained focus on developing psychometrically sound instruments that account for all levels (i.e. theoretical and operational) and aspects of fidelity of intervention implementation is imperative to strengthen the methodological literature for interventions research; and for researchers to correctly interpret research findings and to arrive at valid conclusions on the effectiveness of interventions, whether simple or complex.
A Brief Follow-Up Report on 228 Medial Rotation Total Knee Replacements at a Mean of 8.5 Years (0 - 19)  [PDF]
Sarah McMahon, Gareth Scott
International Journal of Clinical Medicine (IJCM) , 2015, DOI: 10.4236/ijcm.2015.612121
Abstract: We present an update in our earlier report on the Medial Rotation Total Knee Arthroplasty (TKA) when a cohort of 228 TKAs in 189 patients (78 M; 111 F) with a mean age of 67.9 years (28 - 90) was reported at a mean follow-up of six years (1 - 13). At that time, the ten-year survivorship for revision for any reason was 94.5% (95% confidence interval (CI): 85.1 - 100), but only 21 knees were at risk at that tenth year. The 10th annual report of the National Joint Registry (NJR) of England, Wales and Northern Ireland reported a deterioration in survivorship of the Medial Rotation TKA beyond the seventh year of follow-up. This implant previously had enjoyed the lowest rate of revision for any reported brand of prosthesis. As a result, we undertook a comprehensive audit of our original cohort at a mean follow-up of 8.5 years (0 - 19). With revision for aseptic loosening, and revision for any reason as the endpoints, with 125 prostheses at risk at ten years, the ten-year survivorship was 96.7% (95% CI: 93.3 - 100) and 92.3% (95% CI: 87.7 - 93.7) respectively. We have confirmed a decline in survivorship at ten years compared to our initial report. We believe that our results probably provide a more accurate picture of the longevity of the implant than figures available from the NJR, as they are based on detailed contemporary enquiries into each patient’s circumstances. Only ten knees in seven patients were lost to follow-up in our review.
