Examination of E-Learning Success in the Higher Education Environment: A Case Study

To compete in today’s Internet-based society, almost every college and university offers an online-based option of study whether it is a complete university experience, an entire degree program, specific course offerings, individual course sections, or web-based components used to enhance face-to-face learning. Many universities, and their faculty, have hastened to develop and keep updated online materials, yet have not stepped back to examine the materials from the end users’ perspective. In this document, the authors build upon established research to apply the organizational e-learning success model developed by Wang, Wang, and Shea (2005) to the online learning environment at a regional Midwestern university with a population of approximately 10,500 students.
Adult medical x-ray dose assessments for computed tomography procedures in Ghana - A review

Adult Computed Tomography (CT) examinations and dose assessments for head, chest, abdomen, lumbar spine and pelvis at six CT Facilities in Ghana were undertaken (with approval from management of the participating hospitals). The dosimetric parameters estimated were volume computerized tomography dose index (CTDIvol), dose length product (DLP), and effective dose (E) for the stochastic radiation risk of a non-uniform exposure in terms of whole body exposure. For the 39429 examinations, routine head and chest accounted for 50.6 % and 17.0 % frequency, while abdomen, lumbar spine and pelvis accounted for 11.3 %, 10.9 %, and 10.6 % respectiv-ely. Among the Facilities, CTDIvol, DLP and E values varied respectively by a factor of 2.7 for chest and abdo-men, 3.5 for chest and 3.4 for chest. The mean CTDIvol for all the examinations and mean DLP values for head, abdomen and lumbar spine were below the European Commission diagnostic reference levels, while mean DLP of chest and pelvis exceeded the reference levels by 2 and 6 % respectively. With increase in frequency of CT examinations in Ghana, National Reference Levels should be established for patient dose management system.

Results: the proposal with the protocol early implementation with exercises for the comorbidities prevention related to breast câncer treatment helped in clinical and functional parameters improvement. There was no quality of life decline even with the systemic treatment. There was parameters improvement related to satisfaction with health, the ability to daily activities perform, ability to work satisfaction and satisfaction with themselves. Conclusion: the physical therapy must start early and this protocol promoted quality of life maintenance and improved functional capacity of these women.
Gestational trophoblastic disease in a tertiary hospital in Nnewi, southeast Nigeria

Objective: This study was conducted to evaluate the prevalence of GTD and describe its clinical features and management in a tertiary level hospital in Nnewi Southeast Nigeria. Methods: We studied retrospectively the cases of GTD that were proved histologically and managed in the department of Obstetrics and Gynaecology of Nnamdi Azikiwe University Teaching Hospital Nnewi over a 5years period (200 - 2008). Results: The frequency of GTD in Nnewi is 4.6 per 100 deliveries. Ten (66.7%) of the cases were choriocarcinoma while 5 (33.3%) were hydatidiform mole. There was no case of invasive mole or placental site trophoblastic tumour (PSTT). The age range of the patients was 15 - 46 years with a mean of 31+ 8.6 years. There was no significant association between age and GTD (X2 = 4.5; p = 0.609) and between Parity and GTD (x2 = 1.87; p = 0.171 ). Most of the patients (73.3%) presented in late second trimester and the commonest mode of presentation was abnormal vaginal bleeding. The symphysio - fundal height was more than the estimated gestational age in 9 (60%) of cases. All the patients made an earlier presentation in different peripheral hospitals and were managed as incomplete miscarriage prior to presentation in our hospital. The average duration of follow - up in these patients was 2.4 =3.2 weeks. Contraception use was documented in 3 (20%) of the patients. Conclusion: There was a high prevalence of GTD and notably choriocarcinoma. The associated mortality was high. There was lack of suspicion of the pathology among the primary healthcare providers. This study suggests that all cases of evacuation products should be subjected to histopathological examination. There is the need to emphasize the role of adequate and appropriate counselling in the management of the patients with GTD. Call and recall system should be introduced in the management of patients with GTD to improve their compliance to recommended management standard. This will improve the prognosis of the condition in our women. Niger Med J. Vol. 50, No. 4, Oct. - Dec., 2009: 87–89 Key words: gestational trophoblastic disease, tertiary hospital Southeast Nigeria.
Improving civil jury decision-making : evidentiary and procedural issues

OF THE DISSERTATION IMPROVING CIVIL JURY DECISION-MAKING: EVIDENTIARY AND PROCEDURAL ISSUES by Julian A. Gilbert Florida International University, 2006 Miami, Florida Professor Kevin O'Neil, Major Professor The civil jury has been under attack in recent years for being unreliable and incompetent. Considering the myriad causes for poor civil juror decision-making, the current investigation explores both procedural and evidentiary issues that impact juror's decisions. Specifically, the first phase of this dissertation examines how jurors (mis)use evidence pertaining to the litigants when determining liability and awarding damages. After investigating how jurors utilize evidence, the focus shifts to exploring the utility of procedural reforms designed to improve decision-making (specifically revising the instructions on the laws in the case and bifurcating the damage phases of the trial). Using the results from the first two phases of the research, the final study involves manipulating pieces of evidence related to the litigants while exploring the effects that revising the judicial instructions have on the utilization of evidence in particular and on decision-

Children's and young people's experiences of being in hospital : disruption, uncertainty, powerlessness and restoring equilibrium

Whilst the Government has made explicit its stance towards identifying and taking into account the views of children and young people as service users it appears, within some hospital settings, that few openings are available to many children and young people, particularly those with learning or physical disabilities and acute illnesses. This qualitative study used an ethnographic approach to explore 46 children and young people's experiences of being in hospital. Data were collected within the hospital setting through unstructured participatory observation and semi-structured interviews alongside a variety of methods and activity based techniques. The data were collected and analysed concurrently in order to explore emerging themes in the analysis. The children and young people were diverse in terms of age ranges, experience of being in hospital and illness, with some being acutely ill and others having long term chronic illness. The findings revealed that children and young people experienced disruption due to being in hospital. This was experienced as a complex variety of factors, situations and people impacting upon their experiences. Interwoven within this disruption were feelings of powerlessness and uncertainty. Children and young people described experiencing disruption, uncertainty and powerlessness in terms of being in hospital, being ill and undergoing treatment and experiences of care and caring. In order to reduce these experiences children and young people undertook a range of strategies and actions in an attempt to restore equilibrium including "influencing", "accepting", "acting" and "positivity". Within this study I bring together for the first time the ways in which being in hospital creates disruption for children and young people and their agency and capacity in mediating their resultant experiences of powerlessness and uncertainty. I also provide an explanation for the ways in which children and young people experience disruption and restore equilibrium by drawing on Bronfenbrenner's work. The findings have implications for children's nursing in terms of quality and delivery of care for children and young people in hospital.
Occupational asthma in labourers employed at cement industries in Tadiparti Mandal of Anantapur district Andhra Pradesh, India.

Production process in the factory involves three main work stations cranes, crusher and packing, kiln and raw mill, and maintenance of machinery. Exposure to cement dust is likely to vary in the different stages of production process. Therefore in order to understand the variation in dust exposure and the risk of developing of respiratory disorders in work place, three main work stations were selected form which the magnitude of variability in dust exposure was assessed within labourers and between labourers. Several prevalence studies have suggested an association between occupational exposure and respiratory symptoms and asthma, but there has been a lack of incidence studies to verify this. This study examined the incidence of respiratory symptoms, asthma and to explore the respiratory morbidity in terms of symptoms in chronic exposed labourers working in cement industry for more than 11 years.

Oportunidades de aprendizaje y rendimiento en matemática de los estudiantes de tercero y cuarto grados de primaria en Lima y Ayacucho

Las últimas dos evaluaciones nacionales realizadas en el Perú (UMC y GRADE 2001a y 2001b) y las evaluaciones internacionales realizadas por la UNESCO (UMC y GRADE, 2001c) y la OCDE (PISA, 2003) han mostrado que, por lo general, el rendimiento de los estudiantes en matemática y lenguaje (o comunicación, como se denomina a esta área en el currículo de primaria) es pobre en comparación con lo que debería ser, dado el currículo vigente o el rendimiento estudiantil en otros países.
Exploring the Relationships Between Different Types of Facebook Use, Perceived Online Social Support, and Adolescents’ Depressed Mood

This study aims to provide a deeper understanding of the relationships between different types of Facebook use, perceived online social support, and boys’ and girls’ depressed mood. To address this aim, this study (N = 910) developed a comprehensive model that (1) differs between specific types of Facebook use, (2) examines the mediating role of perceived online social support, and (3) takes adolescent users’ gender into account. Structural equation modeling showed that the harmful impact of Facebook use exclusively occurs among girls who passively use Facebook and among boys who actively use Facebook in a public setting. Girls, however, who actively use Facebook, either in a public setting or in a private setting and subsequently perceive online social support, benefit from actively using Facebook, as perceived online social support negatively predicted girls’ depressed mood. The discussion focuses on the explanation and understanding of these findings, key limitations, and directions for future research.

Clinicopathologic Characteristics and Prognosis of Early Stage Triple Negative Breast Cancer: Comparison with Non-triple Negative Group

Purpose: Triple negative breast cancer (estrogen receptor-negative, progesterone receptor-negative, and HER2/neu negative) is associated with high risk of recurrence and poor prognosis. We investigated the characteristics and prognosis of triple negative early-stage breast cancer. Methods: We reviewed the records of 821 early-stage breast cancer patients treated at our hospital from 1995 to 2005. We studied the differences between a triple negative group compared with a non-triple negative group. Results: Of 821 early-stage breast cancer patients, 200 (24.4%) were classified as triple negative. Large tumors (＞2 cm) in the triple negative group were significantly more than those in the non-triple negative group (P=0.042). Histologic and nuclear grade of the triple negative group were significantly higher than those of the non-triple negative group (P＜0.001). The median follow-up time is 50 months (1∼135). There have been 50 local recurrences, 98 distant metastases, and 65 deaths. There were high rates of local recurrence in the triple negative group but no difference in 5-year disease free survival rates (P=0.178). The 5-year overall survival rate showed 85% in the triple negative group but 92.8% in the non-triple negative group (P=0.008). The relative risk for overall survival was 1.93 times higher in the triple negative group. Conclusion: Triple negative breast cancer patients in early stages have poor pathologic findings and prognoses. Careful treatment and follow-up are important and further investigation is necessary for triple negative breast cancer.

The Relation of Fast Food Eating Habits, Physical Activity And Nutrition Knowledge With The Nutritional Status of First Year Medical Student of University of Lampung 2013

High level of activity causes people prefer things that are instant, including in choosing food.Fast food is very easy to get and does not require a long time to be served.Most fast foods are high in calories, cholesterol, fat, and salt but low in fiber.This certainly affects the nutritional status where the incidence of malnutrition is more likely to be higher. Nutrition knowledge level of person also affects attitudes and behaviors in choosing foods. The purpose of this research is to know the relation of fast food eating habits, physical activity and nutrition knowledge with nutritional status of medical student of first year medical student of university of lampung 2013. This research is descriptive analytic research with cross sectional design. The number of respondents are 125 people. The results of this research showed that 58.4% of respondents are often eating fast food and 41.6% respondents are rarely. Physical activity brings about 42,4% have good physical activity and 57.6% have less physical activity and nutritional knowledge gained to 55.2% have good nutrition knowledge, 28% have medium nutrition knowledge and 16.8% have low nutrition knowledge and for nutritional status, 40% have overweight nutritional status, 33.6% normal and 16.5% underweight. The habit of eating fast food, physical activity, and nutritional knowledge has no statistically meaningful relationship (p > 0.05). Key words : fast food, nutrition knowledge, nutritional status, physical activity
Out‐of‐home care among immigrant children in Sweden: a national cohort study

We used data from several national registers for ten entire birth cohorts (n > 1 million) to examine the representation of first generation immigrant children among first time entries into out-of-home care (foster or residential care) at ages 7–12 and 13–17. Logistic regression models were used to adjust results for socioeconomic background factors. Immigrant children were categorised in six groups relating to birth country/continent. Compared with Swedish-born peers, immigrant children from non-European countries had between two- and three-fold sex and birth-year adjusted odds for being placed in care for the first time at ages 7–12. After adjustments for five socioeconomic background variables, none of these overrisks remained. Instead there was a tendency towards immigrant background being associated with reduced risks, statistically significant for immigrant children born in non-Nordic European countries. Immigrant children had between two- and six-fold age and birth-year adjusted odds for entering care for the first time during adolescence. After adjusting the results for socioeconomic background, only immigrant children born in Sub-Saharan Africa or in Asia outside the Middle East had significant overrisks for care entries at ages 13–17 (odds ratio = 1.5).
Prototypes and production rules : a knowledge representation for computer consultations

Abstract : This thesis presents a system called CENTAUR, which demonstrates the effectiveness of representing prototypical knowledge in a combination of frames and production rules for performing computer consultations. Key knowledge representation and control structure problems in production rule systems similar to MYCIN are identified, and a set of important characteristics of the structures used for representing problem-solving knowledge is given. CENTAUR's frames, or prototypes, complement the production rules to satisfy these characteristics and represent expected patterns of data that permit a more focused, hypothesis-directed approach to problem solving. Among the characteristics identified as desirable in the representation structures are the ability to explicitly represent (a) prototypical cases, (b) the context in which knowledge is applied, and (c) the strategies for applying that knowledge. CENTAUR's prototypes consist of patterns of knowledge in the domain which serve as broad contexts, guiding the more detailed processing of the production rules. Strategies for the consultation, or control knowledge, are represented in the prototypes separately from other kinds of domain knowledge. This allows the domain expert to specify control knowledge that is specific to each prototype. Examples are presented which demonstrate how this explicit representation facilitates explanations of the system's reasoning. Further, the organization of knowledge in CENTAUR provides a useful framework for acquiring new knowledge.
Investigating critical sense in the interpretation of media graphs

This research explores elements and processes involved in interpretation of media graphs. The investigation was comprised of a literature review and a collection of empirical data. The literature review revealed a lack of qualitative evidence related to the complex relationships between elements and processes which comprise the interpretation of media graphs. This study explores the interpretation of media graphs by primary student teachers who would be involved in teaching about graphing. The main study was composed of two complementary datasets: questionnaires and interviews, which allowed an interplay between qualitative and quantitative data. 218 undergraduate and PGCE student teachers from Britain and Brazil responded to a questionnaire with items related to individual details, reading background and media graph tasks. 13 volunteers gave interviews which explored three types of questions: reading the data, reading between the data and reading beyond the data. The interviews also recalled the questionnaire responses. The data analysis of the questionnaires was software based, and a micro analysis approach was developed with the data from the interviews. The analyses of data gave evidence for the discussion about the notion of critical sense in graphing. It was concluded that critical sense in interpretation of media graphs is related to the mobilisation and balance of several aspects, such as: mathematical knowledge, contextual reference, personal experience and affective exhibition. The discussion of the results might help the reflection about teaching and learning of graphing in ways that will support the development of critical sense.
CMOS Transmitters for 2.4-GHz RF Devices: Design Architectures of the 2.4-GHz CMOS Transmitter for RF Devices

The fully integrated complementary metal-oxide-semiconductor (CMOS) transmitter (Tx), an essential component in every wireless communication system, ensures highly efficient signal processing and data transmission. The performance of the Tx significantly affects the overall performance of the wireless device [1]. The demand for low-power, low-cost wireless devices operating at the 2.4-GHz band has led to extensive research on RF architecture and circuit design. A well-defined architecture, including linear and simple functional block synthesis, is crucial to the design of the RF Tx for various applications [2]. The state-of-the-art CMOS Txs proposed in the literature to improve Tx performance analyses are vital to understanding application-oriented RF Tx design techniques for further research.
