Age distribution, polyps and rectal cancer in the Egyptian population-based cancer registry
Darlene Veruttipong,Amr S Soliman,Samuel F Gilbert,Taylor S Blachley
World Journal of Gastroenterology , 2012, DOI: 10.3748/wjg.v18.i30.3997
Abstract: AIM: To describe the clinical and epidemiologic profiles of the disease and to compare the findings with those generated from the previous hospital-based studies. METHODS: The Gharbiah cancer registry is the only population-based cancer registry in Egypt since 1998. We analyzed the data of all colorectal cancer patients included in the registry for the period of 1999-2007. All medical records of the 1364 patients diagnosed in Gharbiah during the study period were retrieved and the following information abstracted: age, residence, diagnosis date, grade, stage, topology, clinical characteristics, and histology variables. Egyptian census data for 1996 and 2006 were used to provide the general population’s statistics on age, sex, residence and other related demographic factors. In addition to age- and sex-specific incidence rate analyses, we analyze the data to explore the incidence distribution by rural-urban differences among the 8 districts of the province. We also compared the incidence rates of Gharbiah to the rates of the Surveillance Epidemiology and End Results (SEER) data of the United States. RESULTS: Over the 9 year-period, 1364 colorectal cancer cases were included. The disease incidence under age 40 years was relatively high (1.3/105) while the incidence in the age groups 40 and over was very low (12.0/105, 19.4/105 and 21.2/105 in the age groups 40-59 years, 60-69 years and > 70 years, respectively). The vast majority of tumors (97.2%) had no polyps and 37.2% of the patients presented with primary lesions in the rectum. Colorectal cancer was more common in patients from urban (55%) than rural (45%) areas. Regional differences in colon and rectal cancer incidence in the 8 districts of the study province may reflect different etiologic patterns in this population. The registry data of Egypt shows a slightly higher incidence of colorectal cancer than the United States in subjects under age 40 years. The results also shows significantly lower incidence of colorectal cancer in subjects over age 40 years compared to the same age group in the United States SEER. CONCLUSION: Low rate of polyps, low incidence in older subjects, and high rate of rectal cancer in Egypt. Future studies should explore clinical and molecular disease patterns.
Similarities and Differences between Adult and Child Learners as Participants in the Natural Learning Process  [PDF]
Darlene McDonough
Psychology (PSYCH) , 2013, DOI: 10.4236/psych.2013.43A050
Abstract:

This paper compares Brian Cambourne’s Conditions of Learning (1988), APA’s Learner-Centered Psychological Principles (1997), and Malcolm Knowles’ Adult Learning Theory (2011). These theories embrace the natural learning process and not the traditional view of learning. The traditional view suggests that the teacher has the knowledge, the learner is dependent on the teacher to disseminate the knowledge and the learner has nothing to contribute. In the natural learning process, knowledge is distributed in a circular and reciprocal way through a collaborative sharing of experiences, centered on real life situations, and learners are responsible for their own learning. In the 21st century knowledge is constantly changing and expanding exponentially. The natural learning process facilitates the life-long learning that is needed to remain a valuable contributor in society where learning has become a collaborative experience.

Chairote YAIPRASERT,Krisanadej JAROENSUTASINEE,Tawat VERUTTIPONG
Walailak Journal of Science and Technology , 2005, DOI: 10.2004/vol2iss1pp99-113
Abstract: The Princeton Ocean Model (POM) was modified to simulate motion of a group of particles floating on the sea surface in the Gulf of Thailand. The particles in this group were set up so that they formed a circle. The radius reflected uncertainties of longitude and latitude directions while the centre was set at the point of interest. POM was incorporated with tidal forcing on the boundary, which included used current forcing on the inflow by wind velocities, high resolution and realistic ocean bottom topography, temperature and salinity. The model domain for the Gulf of Thailand extended from latitude 3°N-14°N and longitude 99°E-109°E. A horizontal grid resolution of 0.1 degree (approximately 11.1 km) was used in the model. Therefore, the grids consisted of 101×111 cells. Twenty one levels in sigma coordinate were used in vertical resolution. The model results were verified using TOPEX/Poseidon and JASON satellite data. The results of the simulation were used to gain a better understanding of the sea current and object movement patterns in the Gulf of Thailand.
The Importance of Long-Term Social Research in Enabling Participation and Developing Engagement Strategies for New Dengue Control Technologies
Darlene McNaughton
PLOS Neglected Tropical Diseases , 2012, DOI: 10.1371/journal.pntd.0001785
Abstract: Background In recent years, new strategies aimed at reducing the capacity of mosquito vectors to transmit dengue fever have emerged. As with earlier control methods, they will have to be employed in a diverse range of communities across the globe and into the main settings for disease transmission, the homes, businesses and public buildings of residents in dengue-affected areas. However, these strategies are notably different from previous methods and draw on technologies that are not without controversy. Public engagement and authorization are critical to the future success of these programs. Methodology/Principal Findings This paper reports on an Australian case study where long-term social research was used to enable participation and the design of an engagement strategy tailored specifically to the sociopolitical setting of a potential trial release site of Wolbachia-infected Aedes aegytpi mosquitoes. Central themes of the social research, methods used and conclusions drawn are briefly described. Results indicate that different communities are likely to have divergent expectations, concerns and cultural sensibilities with regard to participation, engagement and authorization. Conclusions/Significance The findings show that a range of issues need to be understood and taken into account to enable sensitive, ethical and effective engagement when seeking public support for new dengue control methods.

‘Spaces of resistance'– African workers at Shoprite in Maputo and Lusaka
Darlene Miller
Africa Development , 2006,
Abstract: South Africa's reintegration into Southern Africa since 1994 has opened the way for renewed investments by South African firms in African countries. New shopping malls are one visible impact of this post-Apartheid development. This article is about the regional claims and the regional resistance of workers at the foreign branches of Shoprite, a South African retail multinational. Two shopping mall workplaces of Shoprite in Zambia (Manda Hill) and Mozambique (Centro Commercial) are the case studies for this analysis. The paper compares the experiences of retail workers at Shoprite, a South African food supermarket chain and Africa's largest retailer, in two cities – Maputo, Mozambique and Lusaka, Zambia, exploring the variations and similarities in the responses of workers to their South African work environments. While Zambia's ‘expectations of modernity' have led to disillusionment, Mozambican workers accept South African investment as a necessary phase of Mozambique's recovery. I argue that a new regional moment is shaping the workplace experiences of African workers, opening up a new ‘space of hope' in the region. South African retail multinational corporations are important agents of a new regional imagination amongst retail workers in post-Apartheid Southern Africa. Africa Development Vol. 31(1) 2006: 27-49
Resilience and Risk
Darlene Brackenreed
International Education Studies , 2010, DOI: 10.5539/ies.v3n3p111
Abstract: In the age of the human Genome Project wide spread prodigious information technology, our system of education is unable to keep pace with and meet the demands for knowledge, skills, and identification and treatment of academic, emotional, social, mental and health concerns of our youth. As the Saskatchewan task force on the state of education in Saskatchewan, Canada (1999) noted, the educational system's problems mirror those problems found in society in general. Increasingly, these societal problems are being deferred to the educational institutions for identification, treatment and prevention. While all parties tend to agree that prevention of problems is desirable, there is not general agreement about the efficacy of prevention programs rather than deficit models, nor the means by which to develop resilient students. The purpose of this paper is to identify risk factors and their potency, to identify protective or resilient factors and their potency, to identify the relationship and relevancy of these two concepts for students, and to identify family, community and school practices that foster resiliency.
Amalgamethodology: A Research Methodology Unique to Nursing Fostering Critical Thinking Implications for Education and Practice
Darlene Sredl
Journal of Applied Medical Sciences , 2013,
Abstract: The basic sciences have relied upon quantitative research methods since the scientific method surfaced in the 17th century. Reverend Bayes posited what we now know as Bayes’ Theorem to provide the underpinnings for the scientific evidence-based process. Nursing is a relative newcomer on the scientific discipline chart, but an important one none-the-less. In the roughly 160 years since its inception, nursing has striven to build a knowledge base unique to its composite meta-paradigm (person, health, nursing & environment). Within the last half-century, qualitative research methods have evolved, among them: phenomenology, feminist & gender studies, ethnography, and grounded theory methods. A need has been identified for the science of nursing to utilize its’ own methodology for research. Amalgamethodology is the research design proposed as unique to the science of nursing. This article defines Amalgamethodology, discusses its core components, identifies the importance of graphic representation within the design, and suggests research utilization scenarios to build the evidence-base for this research design unique to the science of nursing. Implications for the future of nursing research, education, and practice are discussed.
Successful versus Unsuccessful Schools through the Eyes of Children: The Use of Interviews, Autophotography, and Picture Selection
Darlene DeMarie
Early Childhood Research & Practice , 2011,
Abstract: Although “top-down” indicators, such as the ratio of adults to children in classrooms and program rankings based on standardized test scores, can predict some of the future impact of children’s education, “bottom-up” factors, such as whether children feel welcome and whether they find the learning activities to be meaningful and engaging, may have a greater effect on children’s long-term development. Yet little is known about children’s perceptions of their schools and how their views may differ depending on the type and quality of schools they attend. In the present study, three methods—interview, autophotography, and picture selection—were employed to learn about children’s perceptions of their schools and whether their perspectives differed depending on whether they attended schools labeled “successful” or “unsuccessful.” The 156 participants in kindergarten to fifth grade (ages 5 to 11) were interviewed about their school experiences. In the context of making books about their schools, children took photographs that they felt would show others what the schools were like. They also selected photographs from a standardized set of other photographs—one they thought “best showed” their school and one that showed what was “most important” to them. The following were among the results: (1) Participants at the unsuccessful school were more likely to identify school as being about academics and evaluation/tests and less about play/fun, especially in the early grades. (2) The importance of friendships was more evident among children at the successful school than among children at the unsuccessful school. (3) Among participants from both schools, the pictures that children selected that “best showed” their school usually differed from what was “most important” to them.
A Trip to the Zoo: Children's Words and Photographs
Darlene DeMarie
Early Childhood Research & Practice , 2001,
Abstract: Field trips are a regular part of many programs for young children. Field trips can serve a variety of purposes, such as exposing children to new things or helping children to see familiar things in new ways. The purpose of this study was to learn the meaning children gave to a field trip. Cameras were made available to each of the children in a group of 3- to 12-year-olds (n = 21) from a campus child care center. It was suggested to them that they take pictures during the field trip to show other children, who were unable to go on the trip, what the zoo was like. Trips to the zoo were not a regular part of the center's program. The results revealed that over 80% of 6- to 12-year-olds' photographs contained animals. Older children noticed and learned new features of familiar animals and about new, unfamiliar animals. Only the 10- to 12-year-olds indicated that they understood abstract concepts such as the need to preserve animals. On the other hand, with one exception, only 56% of the preschool children's photographs contained animals, and they photographed only familiar animals, including chipmunks. They photographed action (e.g., swimming, petting). Young children also photographed the clouds, ground, and other items not uniquely associated with the zoo. The results were interpreted in light of Farrar and Goodman's Schema-Conformation Deployment Model. Preschool children seem to need more than one exposure to unfamiliar phenomena to notice and to remember them.
