Andragogy and Engagement in Online Learning: Tenets and Solutions  [PDF]
Barry Chametzky
Creative Education (CE) , 2014, DOI: 10.4236/ce.2014.510095
Abstract: In this paper, the author discusses two tenets of online learning: andragogy and learner engagement. What are the foundational principles of these educational practices? In light of the discussed foundational principles, the author examines various techniques which educators could use in order to help online learners succeed in the often-stressful environment. Ultimately, educators want learners to reach the pinnacle of Bloom’s Taxonomy pyramid; by following the suggestions presented in this paper, educators will help learners accomplish this objective. Yet, more research is needed in this area. Therefore, the recommendation is for further study in the relationship between andragogy and the varied mesh of ideas associated with meaningfulness and engagement.

Coding in Classic Grounded Theory: I’ve Done an Interview; Now What?  [PDF]
Barry Chametzky
Sociology Mind (SM) , 2016, DOI: 10.4236/sm.2016.64014
Abstract: Without a doubt, many graduate students—especially those who do not have a mentor skilled in the classic grounded theory design—are concerned about doing studies or dissertations using the classic grounded theory design for fear of doing them incorrectly. While there is extant literature in the field of classic grounded theory, a clear and simple how-to does not exist. The purpose of this paper is to give novice researchers interested in the classic grounded theory design a foothold in how to do one aspect of classic grounded theory analysis: coding. The explanation offered in this paper is based in theory and supported with practical examples.
The Online World Languages Anxiety Scale (OWLAS)  [PDF]
Barry Chametzky
Creative Education (CE) , 2019, DOI: 10.4236/ce.2019.101005
Abstract: Sadly, anxiety and stress exist all around us. While anxiety has previously been studied in traditional foreign language environments, no information exists about anxiety in an online foreign language environment. Withouthaving a detailed understanding of potential problems in an online environment, educators, administrators, and course designers would not be able to help struggling, suffering students. Thus, the purpose of this seven-participant pilot study was to develop a more refined understanding of foreign language anxiety in the online learning environment. In some respects, the results of this?study confirm what foreign language educators already know: students prefer writing rather than speaking, interacting with the instructor rather than with peers, and keeping up with the work is sometimes a challenge. Additionally, if students don’t know basic grammatical elements in their native language,?there may be issues in the target language. Yet, researchers can now begin to understand additional components of anxiety that were not examined previously in online foreign language courses in a more nuanced manner.
Delayed Thoracic Radiation Injury  [PDF]
Barry Dicicco
International Journal of Clinical Medicine (IJCM) , 2012, DOI: 10.4236/ijcm.2012.36094
Abstract: A case of delayed thoracic radiation injury occurring many years after an initial lung insult is presented. This case involves an individual who developed acute respiratory failure due to severe pleural fibrosis or fibrothorax possibly as a result of distant radiation therapy for Hodgkins disease.
Do Patients with Asymptomatic Congenital Complete Heart Block Require a Pacemaker for Non-Cardiac Surgery?  [PDF]
Barry Swerdlow
Open Journal of Anesthesiology (OJAnes) , 2018, DOI: 10.4236/ojanes.2018.84014
Abstract: The appropriate preparation of the patient with asymptomatic congenital complete heart block (CCHB) and a narrow QRS complex for elective non-cardiac surgery is controversial. Prophylactic temporary pacemaker insertion is associated with well-defined risks, and less invasive techniques exist to treat transient, hemodynamically significant intraoperative brady-arrhythmias. The present case report details the performance of general anesthesia for arthroscopic knee surgery in an adult patient with this condition without a pacemaker. Documentation of preoperative chronotropic competence with isoproterenol may be of value in deciding whether to proceed without temporary pacing capability in this setting.
Innovation and Co-Creation Process within a Service Context: A Matter of Choice or Necessity?  [PDF]
John McManus, Barry Ardley
Open Journal of Business and Management (OJBM) , 2019, DOI: 10.4236/ojbm.2019.71002
The notion of service ought to be embedded in the psyche of those responsi-ble for the design and delivery of service provision. Within an ever changing landscape, meeting customer expectations is a major priority for firms en-gaged in service provision. Enhancing the service experience lies in the con-text of innovation and entrepreneurship. The focus of innovation within business should take into consideration the unexpected, the nature of incon-gruities, process need and changes to structure. Innovation within service industries is widely recognised among researchers and practitioners as a key to gaining and sustaining competitive advantage. Increasingly, firms within service industries are placing new knowledge at the core of their strategies, especially knowledge about co-creation processes, knowledge of innovation and service design. In this context, the purpose of this paper is to explore the linkages between service development and co-creation processes to better understand the complexity of service innovation. The paper will first outline the notion of service and the context of service innovation. It will present a summarised view for management of service innovation. The paper will then move to illustrating how the creation and use of co-creation processes can be used to provide a shared understanding of what constitutes best practice.
Incomplete Reporting of HIV/AIDS by Uganda’s Surveillance System and the Associated Factors  [PDF]
Denis Akankunda Bwesigye, Barry M. Loneck, Barry R. Sherman
Open Journal of Preventive Medicine (OJPM) , 2016, DOI: 10.4236/ojpm.2016.64011
Abstract: Introduction: The United States government supported Ugandan government by introducing the District Health Information Software 2 (DHIS2) in 2012 to improve HIV/AIDS surveillance. Districts have yet to fully adopt this relatively new system given a 70.2% reporting completeness achieved nationally between April-June 2013. Methods: The study examined one dependent variable of districts’ reporting completeness against four independent variables: 1) Number of client visits; 2) Number of district health units; 3) Number of NGOs delivering HIV/AIDS services; and 4) Regional location. The study employed cross-sectional study design which allowed researchers to compare many different variables at the same time. HIV/AIDS program data that were reported by districts into DHIS2 during the period of April to June 2013 were used to assess for reporting completeness. Findings: Districts with the lowest number of client visits (under 2500) achieved the highest mean reporting completeness (81.6%), whereas a range of 2501 - 5000, or over 5001client visits recorded 72.4% and 51.7% respectively. The higher the number of client visits is, the lower the reporting completeness is (p < 0.05). Those districts that were receiving support from only one and two NGO recorded 56.7% and 67.2% respectively. Districts supported by over three NGOs had the highest (80.6%) mean reporting completeness. NGOs-district support was statistically associated with reporting completeness (p < 0.05). The number of health units operated by a district was also significantly associated with reporting completeness (p < 0.05). The regional location of a district was not associated with reporting completeness (p = 0.674). Conclusion: The study results led us to recommend targeted future NGO support to districts with higher patient volume for HIV/AIDS services. Particularly, newly funded NGOs are to be established in districts operating over 40 health units. Incomplete reporting undermines identification of HIV-affected individuals and limits the ability to make evidence-based decisions regarding HIV/AIDS program planning and service delivery.
Potential Range Expansion of the Invasive Red Shiner, Cyprinella lutrensis (Teleostei: Cyprinidae), under Future Climatic Change  [PDF]
Helen M. Poulos, Barry Chernoff
Open Journal of Ecology (OJE) , 2014, DOI: 10.4236/oje.2014.49045

We built climate envelope models under contemporary and future climates to explore potential range shifts of the invasive Red Shiner-Cyprinella lutrensis. Our objective was to estimate aquatic habitat vulnerability to Red Shiner invasion in North America under future climatic change. We used presence records from within the species’ native and invaded distributions, a suite of bioclimatic predictor variables from three climate models (CCCma, CSIRO, and HadCM3), and maximum entropy modeling to generate potential distribution maps for the year 2080. Our model predicted major range expansion by Red Shiner under both low and high carbon emissions scenarios. The models exceeded average area under the receiver operator characteristic curve values of 0.92, indicating good overall model performance. The model predictions fell largely outside of areas of climatic extrapolation (i.e. regions predicted into environments different from training the region) indicating good model performance. The results from this study highlight the large potential range expansion across North America of Red Shiner under future warmer climates.

Cargo Airships: International Competition  [PDF]
Barry E. Prentice, Robert Knotts
Journal of Transportation Technologies (JTTs) , 2014, DOI: 10.4236/jtts.2014.43019

The advance of transportation technology depends on science and economics. During the 1930s, airships and airplanes competed head-to-head for the Atlantic passenger market. When World War 2 broke out, everything changed. Over the next five years, the combined combatants built over half of a million military airplanes. By the end of the war, four-engine, high-altitude bombers and jet engines were developed. Further investment in airplane technology was stimulated by the Cold War. All this public investment was adapted to civilian passenger jet airplanes. By 1980, dedicated jet airplanes were in use as cargo carriers. Despite the growth of the cargojet market over the past three decades, rising fuel costs and environmental concerns are changing the economics of airships and airplanes again. Investment in large cargo airships is returning. Much of the technology developed for fixed-wing aircraft can be applied to cargo airships. New materials, better engines, control systems and engineering eliminate the need for large ground crews and improve airship reliability and safety. However, two fundamental design issues have yet to be resolved: structural integrity and buoyancy control. A worldwide competition is underway on three continents to develop the dominant design for a cargo airship. This paper examines the alternative design approaches and presents the status of the international competition.

Containerization of Grain: Emergence of a New Supply Chain Market  [PDF]
Barry E. Prentice, Mark Hemmes
Journal of Transportation Technologies (JTTs) , 2015, DOI: 10.4236/jtts.2015.52006
Abstract: The containerized shipment of freight continues to grow rapidly. This development can be traced to a transformation of bulk and break-bulk service to containerization. Demand has been driven by opportunities to broaden logistical options as well as advantageous freight rates. Logisticians and policy makers are unsure how much more bulk traffic can be converted to containerization, but the trends are evident. Of particular interest is grain. Bulk grain handlers have successfully resisted the conversion of grain shipping to containerization, except on the North American-Asian traffic lanes and the Australian-Asian traffic lanes where growth has been significant. This paper reviews the theoretical case for grain containerization from a logistics perspective, followed by an examination of the current trends in the United States and Canada. Subsequently, the analysis considers the restrictions and resistance to the conversion of grain from bulk shipping to containerization.
