Digital Production and Students as Learning Designers

Today’s digitalization allows users to interact, collaborate, communicate and create user-generated content. The technology is intuitive and easy to use even for young children, and new learning opportunities emerge. Particularly, students’ production as a learning form benefits from digitalization as the new opportunities enable young students to integrate their playing competencies and skills into the formal school learning. This paper presents and discusses a theory regarding students’ digital production from a learning and design-for-learning perspective, which is generated based on the project Netbook 1:1 (2009–2012), where information and communication technology (ICT) was readily accessible for each child at school and at home in grades 1–3 at two Danish public schools. The paper presents a Four Levels Design for Learning Model, which can be used for both design for learning and analyses of learning processes. The discussion is supported by empirical examples from the project, which explored emerging relations amongst ICT, production and subject matter-specific practice (Danish, mathematics and interdisciplinary activities). We understand design for learning as related to both process and agency, and in the study, we have examined and found that students are capable of operating as learning designers.
REVIEW OF TRAJECTORY ACCURACY METHODOLGY AND COMPARSION OF ERROR MEASUREMENT METRICS

The aircraft trajectory is a prediction of the aircraft’s anticipated flight path. Trajectory accuracy is measured by comparing the trajectory prediction to the actual flight path of the aircraft. Trajectory accuracy analysis starts with a sampling process that selects the actual and predicted trajectory positions for measurement and concludes with the application of statistical and graphical analysis methods. At the base of a study are the error measurements and how they are defined. Their definitions are the focus of this paper. Two spatial metrics and two time metrics were specifically defined and compared in the horizontal dimension. Both detailed synthetic flight examples and a large traffic sample were employed to evaluate these error metrics. The second spatial metric and first time error metric proved to be superior methods in turns and approximately equivalent elsewhere. From the traffic sample, the standard deviation of the differences between the presented spatial and time error metrics was significant, ranging from 0.6 to 4.2 nautical miles and 9 to 55 seconds, respectively. Therefore, it is concluded that it is essential to clearly define the particular error measurement technique applied in a trajectory accuracy study to not only be relevant, but also for the results to be extensible and cross comparable with other studies.
Flexible bandwidth allocation in hybrid fiber coax distribution networks

Hybrid fiber/coax (HFC) subscriber networks are a popular architecture for interactive video/multimedia on-demand services. The available downstream bandwidth for data transmission is partitioned into streams, typically 25-50 Mbps, shared by varied traffic of multiple subscribers. Given subscriber receivers that can tune one stream at a time, we show that correlated traffic can significantly increase the probability of blocking. The performance associated with uncorrelated traffic can be retrieved by offloading selected traffic from one stream to another, demonstrating a close association of configuration operations with call processing. We describe an algorithm that achieves this performance.
Chronic Obstructive Pulmonary Disease in Middle East and UAE: An Unrecognized Underestimated Epidemic

Although COPD is not a curable disease, elimination or reduction of risk factors can prevent the development or slow down the progression of the disease. The main risk factors for the development of COPD are cigarette smoking, exposure to air pollutants resulting from the burning of wood or other biomass fuels, tuberculosis, occupational exposures and increasing age [5]. The increase in prevalence of COPD is directly related to the increase in prevalence of smoking worldwide, particularly among women and adolescents.
Feasibility of Retrograde Ureteral Contrast Injection to Guide Ultrasonographic Percutaneous Renal Access in the Nondilated Collecting System.

OBJECTIVES Ultrasound-guided percutaneous nephrolithotomy (PCNL) has become increasingly utilized. Patients with nondilated collecting systems represent a challenge: the target calix is often difficult to visualize. Here we report pilot study results for retrograde ultrasound contrast injection to aid in percutaneous renal access during ultrasound-guided PCNL. PATIENTS AND METHODS From April to July 2016, consecutive patients over the age of 18 years with nondilated collecting systems on preoperative imaging who presented for PCNL were enrolled. B-mode ultrasound imaging was compared with contrast-enhanced mode with simultaneous retrograde injection of Optison™ via an ipsilateral ureteral catheter. RESULTS Five patients (four males and one female) with renal stones underwent PCNL with retrograde ultrasound contrast injection during the study period. Mean body mass index was 28.3 ± 5.6 kg/m2 and mean stone size was 24.5 ± 12.0 mm. Under B-mode ultrasound, all patients demonstrated nondilated renal collecting systems that appeared as hyperechoic areas, where it was difficult to identify a target calix for puncture. Retrograde contrast injection facilitated delineation of all renal calices initially difficult to visualize under B-mode ultrasound. Renal puncture was then performed effectively in all cases with a mean puncture time of 55.4 ± 44.8 seconds. All PCNL procedures were completed without intraoperative complications and no adverse events related to ultrasound contrast injection occurred. CONCLUSION Retrograde ultrasound contrast injection as an aide for renal puncture during PCNL is a feasible technique. By improving visualization of the collecting system, it facilitates needle placement in challenging patients without hydronephrosis. Future larger scale studies comparing its use to standard ultrasound-guided technique will be required to validate this concept.
Role of University Entrepreneurship Programs in Developing Students’ Entrepreneurial Leadership Competencies: Perspectives From Malaysian Undergraduate Students

The authors aimed to identify the role of university entrepreneurship education programs in developing students’ entrepreneurial leadership competencies. A total of 18 interviews were conducted with students and university entrepreneurship program coordinators. From these, 16 prominent roles of the programs emerged and were classified into 2 clusters: student-related and program-related roles. Student-related roles reflect the contributions of the programs in developing personal and interpersonal leadership competencies of students. Program-related roles are the roles that the programs play in organizing and sustaining various entrepreneurial leadership learning opportunities, linking students to the world of entrepreneurial venturing, and having a holistic approach to university entrepreneurship programs.
Trends of MRI use to Evaluate Breast Cancer in the Texas Medicare Population

Background: The availability of Magnetic Resonance Imaging (MRI) has increased in the United States over the last decade. The use of MRI to diagnose and stage breast cancer has not been described. We examined the trends and frequency of MRI use in women with newly diagnosed breast cancer in Texas and evaluated the factors associated with receipt of an MRI. Methods: Medicare-linked data from the Texas Cancer Registry (TCR) were used to identify incident breast cancer cases between Jan. 1, 2003 and Dec. 30, 2007. We included female patients, 65 years and older, enrolled in both Medicare Parts A and B for 3 months prior to diagnosis and 12 months after diagnosis, and not enrolled in an HMO plan during that period. Patients diagnosed at autopsy were excluded. Bivariate and multivariate logistic regression analyses were performed to determine the factors associated with receipt of MRI within 3 months before and after diagnosis. A Cochran-Armitage trend test was performed to examine the trends in use of MRI by year. A value of P<0.05 was considered statistically significant. Results: Of the 18,856 patients meeting inclusion criteria, 1,268 (6.72%) received an MRI. The use of MRI increased significantly in Texas from 2.25% of women diagnosed in 2003 to 13.9% in 2007 (P<0.0001). Bivariate analysis revealed that age, race, number of comorbidities, income, education, and urban/rural location were associated with the receipt of MRI at the time of breast cancer diagnosis. In multivariate analysis, odds of receiving an MRI were lower in women of advanced age (odds ratio [OR] 0.098; 95% Confidence Interval [CI] 0.044-0.223), black race (OR 0.66; 95% CI: 0.49-0.88) and the presence of two or more comorbid conditions (OR 0.30; 95% CI; 0.19-0.48). Those with regional disease and a higher level of education were more likely to receive MRI. Conclusion: Use of MRI in patients with newly diagnosed breast cancer in Texas increased six-fold during the study period, but increases varied across racial groups.

Reevaluation of serum carnitine status in patients with liver cirrhosis

Background:Carnitine (CA) is an important key substance for lipid metabolism and serum CA levels change in patients with various diseases. Although liver cirrhosis (LC) is known as a representative cause of secondary CA deficiencies, the exact levels of serum CA in LC patients remains a controversial issue. The aim of the present study was to reevaluate the serum CA levels in LC patients, with a particular focus on the relationship between serum CA levels and liver and renal function. Methods:Seventy-one patients with LC (51 males, 20 females; median age 63.0 years) were examined. Fasting serum Total-CA (T-CA), Free-CA (F-CA) and Acyl-CA (Ac-CA) levels were measured using an enzymatic cycling method and were evaluated according to their relationships with liver and renal dysfunction. Results:The levels (mean ± standard deviation, μmol/L) of serum T-CA, F-CA and Ac-CA (72.9±19.1, 55.3±14.0 and 17.6±7.2 respectively) in LC patients were almost within normal range (T-CA: 45.0-91.0; F-CA: 36.0-74.4 and Ac-CA: 6.0-23.0 respectively). Approximately 11% of patients had serum T-CA levels <45μmol/L. These serum CAs levels did not correlate with severity of liver damage based on the Child-Pugh classification and the Model for End-stage Liver Disease, but serum T-CA and Ac-CA levels significantly correlated with serum creatinine and/or the estimated glomerular filtration rate. Blood ammonia levels did not correlate with these serum CA levels. Among nutritional parameters, only serum free fatty acid levels strongly correlated with serum Ac-CA levels and the Ac-CA to T-CA ratio. Conclusion:Our results suggest that the rate of secondary CA deficiency may be low and that serum CA levels are almost within normal range in LC patients, although serum Ac-CA levels are closely associated with renal dysfunction. Furthermore, the Ac-CA to T-CA ratio may be useful as a marker of malnutrition (299).
A Comprehensive Survey of Noun Phrase Chunking in Natural Languages

— Assamese being an official language in the Indian State Assam, is a computationally less aware language. Almost 13 Million peoples speak this language around the world. In spite of being a morphologically rich and agglutinative language, very limited research work has been done in Chunking of Assamese Sentences in the domain of Natural Language Processing. NP Chunker deals with extracting the Noun Phrases from a sentence. Though NP Chunker is much simpler than parsing, building an accurate and fast NP Chunker is difficult as well as a challenging task. The main objective of this paper is to highlight the works done in Chunking of Indian Languages and other than Foreign Languages.
Aerosol profile variations retrieval through Kernel functions in the oxygen absorption band at 762 nm

The aerosol kernel functions, relating (through a Fredholm integral equation) the variations in radiance measured by satellites to the variations of aerosol extinction profile, have been computed with a 20 cm/sup -1/ spectral resolution within the Oxygen A-band (LOWTRAN atmospheric database has been used). The kernel was originally evaluated at wavelengths in the near infrared region outside absorption bands. Notwithstanding the fact that a higher spectral resolution should be adopted to fully take advantage of the Oxygen band possibilities, even the 20 cm/sup -1/ resolution permits a better information content and an improved accuracy with respect to the wavelengths previously investigated: indeed the retrieval relative error is approximately reduced by a half.
Prevalence of Dermatophytosis in Rabbits at SAQTVH, Chittagong, Bangladesh

under light microscope in400 magnifications to observe fungal morphology. Rest of the samples was preserved at room temperature (25°c) in zipper bag for fungal isolation and identification. Sabouraud’s dextrose agar plates, containing 0.02% Cycloheximide and 0.3% Depomycin was used to fungal culture and the specific types of funguses were identified based on colony characteristics. Trichophyton mentagrophytes was the most common fungal species isolated from rabbits. Among the suspected patients the prevalence of T. mentagrophytes was 89%. There observed insignificant (p>0.05) effects of sex, age, body weight and deworming status for the occurrence of dermatophytosis in rabbit. The current study limited only on the hospitalized suspected patients, so a comprehensive study considering the sample from whole rabbit population is required to find out the actual prevalence of the fungal species.
Electromagnetic and Electrohydraulic Shock Wave Lithotripsy-Induced Urothelial Damage: Is There a Difference?

PURPOSE To evaluate and compare the acute effect of electromagnetic and electrohydraulic extracorporeal shockwave lithotripsy (SWL) on the urothelial layers of kidney and ureter. MATERIALS AND METHODS Fifty patients, 29 males (58%) and 21 females (42%), with an average age of 51.68 years (range: 37-70) who underwent SWL application in two different centers were included. Twenty-eight patients (56%) were treated with electrohydraulic and 22 (44%) were treated with electromagnetic lithotripsy. Urinary cytologic examinations were done immediately before and after SWL therapy and 10 days later. The average numbers of epithelial cells, red blood cells (RBC), and myocytes were counted under 40 × magnification. RESULTS There were significant differences in the number of epithelial cells and RBC before and after immediate application of SWL: 1.66 and 14.9 cells/field, (p = 0.001), 5.44 and 113.45 cells/field, respectively (p = 0.001). The number of RBC was significantly higher in patients treated with electromagnetic lithotripsy than those treated with electrohydraulic: 141.9 and 93.4 cells/field, respectively (p = 0.02). No myocyte or basement membrane elements were detected in any of the cytologic examinations. Cytologic examinations done after 10 days of SWL therapy revealed recovery of all abnormal cytologic findings. CONCLUSIONS The acute increments in the number of epithelial cells and RBC after SWL were statistically significant but it was not permanent. SWL-induced urinary urothelial lesion is limited to the mucosal layer and there was no evidence of damage to the basal membrane or muscle layer. Electromagnetic lithotripsy caused high numbers of RBC than the electrohydraulic device on the postimmediate urine cytologic examination.
Wayfinding in Libraries: Can Problems Be Predicted?

The main library at the authors’ university campus, with its large size and multiple-level structures, is challenging for patrons to navigate. Requests for directions are among the most frequently posed questions at help desks in this library. As a first step toward improving wayfinding aids, such as maps or signs, we took a spatial science perspective of combining spatial and behavioral approaches to reveal objectively areas where wayfinding problems occur. To this end, we employed formal spatial descriptions of the environment addressing visibility, layout complexity, and connectivity. The term coined in the literature for these methods is “space syntax. ” Additionally, we used a behavioral approach to investigate actual wayfinding behaviors of library patrons and compared these behaviors with the results of the space syntax analysis. The results show that a building's layout complexity and visual access potentially predicts how well patrons find their goals (books and other materials). Other aspects such as signs or individual characteristics of patrons were also found to play a role in understanding human wayfinding performance. The goal of this study was to broadly explore wayfinding problems in relation to the environment and to individual characteristics of patrons, such as their familiarity and sense of direction. Our approach introduces an objective perspective to assess wayfinding problems in libraries. Thereby, it provides potentially valuable information for library administrators towards the improvement of the design of library wayfinding systems.
Impact of interpersonal conflict in health care setting on patient care; the role of nursing leadership style on resolving the conflict

An interpersonal conflict is a disagreement between two persons or subgroups of an organization involving significant bitterness and dissatisfaction. Health care professionals, who understand each other’s roles and can work effectively together, have been shown to provide higher quality care and hence, to achieve desire out comes in patient care, it is essential to have good interpersonal relationship in terms of cooperation, collaboration, listen, and respect the values or positions of each other. Strong and effective leadership styles are key components to any health care success. There are certain situations which demand different leadership approaches. Historian and Burns in 1978 developed transformational leadership theory, which emphasizes the importance of interpersonal relationship. Conflict management is a complex process, which demands time and energy. The management and the subordinates must be concerned and devoted to resolving conflict among coworkers by being willing to listen and to find accurate solutions. To overcome interpersonal conflict in the health care setting requires accurate knowledge and skills for health care professionals to reduce the occurrence of conflict. This paper has implications for nurse leaders and organizations who seek to manage conflict among employees to reduce its negative consequences on working environment and organization productivity.
Rainfall estimation by combining radar and infrared satellite data for nowcasting purposes

The aim is to evaluate the use of infrared satellite precipitation estimates for nowcasting purposes in the context of a real‐time flood‐warning scheme. A radar‐based calibration technique is described which is applied to the Negri–Adler–Wetzel scheme. This procedure employs radar data over a defined calibration area to estimate, for each satellite image, actual rain‐rates to be used in the Negri–Adler–Wetzel scheme. Calibrated satellite estimates obtained from this procedure can be used to diagnose areas of precipitation beyond radar range, thus allowing an extension of precipitation nowcasting lead time. Calibrated estimates are compared with radar rainfall measurements and results are discussed for various sizes of integration area. Calibration reduces consistently both bias and variance of the error of the original Negri–Adler–Wetzel estimates, even for integration areas as small as 2000 km2. This indicates the capabilities of the new technique for nowcasting purposes over mediumsized river basins. Copyright © 1999 Royal Meteorological Society
Collaborative research projects in the technology-enhanced language classroom: Pre-service and in-service teachers exchange knowledge about technology

Abstract This paper presents research findings of a longitudinal empirical case study that investigated an innovative Computer Assisted Language Learning (CALL) professional development program for pre-service English as Foreign Language (EFL) teachers. The conceptualization of the program was based on the assumption that pre-service language teachers learn better in situated contexts (Egbert, 2006). Therefore, a key component of the program was the development of school-based research projects, in which the student teachers needed to design, implement, and evaluate technology-enhanced EFL lessons in collaboration with in-service teachers. Data were collected via field notes, video recordings of lessons, academic research reports produced by the pre-service teachers, and in-depth interviews with the pre-service and in-service teachers. Our findings indicate that the field experiences provided professional learning opportunities that supported the student teachers’ development as CALL practitioners. The participating pre-service teachers especially emphasized the important role played by school-based experiences in allowing them to use technology in authentic language teaching scenarios and to evaluate the impact of technology on language teaching and learning. The paper concludes with a discussion of important principles and guidelines that should underlie and inform such collaborative efforts and a summary of the implications of the findings for the design of CALL pre-service teacher education programs.
