Examining a multidimensional model of student motivation and engagement using a construct validation approach.

BACKGROUND
This study seeks to examine a multidimensional model of student motivation and engagement using within- and between-network construct validation approaches.


AIMS
The study tests the first- and higher-order factor structure of the motivation and engagement wheel and its corresponding measurement tool, the Motivation and Engagement Scale - High School (MES-HS; formerly the Student Motivation and Engagement Scale).


SAMPLE
The study draws upon data from 12,237 high school students from 38 Australian high schools.


METHODS
The hypothesized 11-factor first-order structure and the four-factor higher-order structure, their relationship with a set of between-network measures (class participation, enjoyment of school, educational aspirations), factor invariance across gender and year-level, and the effects of age and gender are examined using confirmatory factor analysis and structural equation modelling.


RESULTS
In terms of within-network validity, (1) the data confirm that the 11-factor and higher-order factor models of motivation and engagement are good fitting and (2) multigroup tests showed invariance across gender and year levels. In terms of between-network validity, (3) correlations with enjoyment of school, class participation and educational aspirations are in the hypothesized directions, and (4) girls reflect a more adaptive pattern of motivation and engagement, and year-level findings broadly confirm hypotheses that middle high school students seem to reflect a less adaptive pattern of motivation and engagement.


CONCLUSION
The first- and higher-order structures hold direct implications for educational practice and directions for future motivation and engagement research.
Effectiveness of Structured Teaching Program on Knowledge , Attitude and Management Strategies Among Teachers of Primary School toward Children with Attention Deficit Hyperactivity Disorders .

Using and validating the strategic alignment model

The literature suggests that firms cannot be competitive if their business and information technology strategies are not aligned. Yet achieving strategic alignment continues to be a major concern for business executives. A number of alignment models have been offered in the literature, primary among them the strategic alignment model (SAM). However, there is little published research that attempts to validate SAM or describe its use in practice. This paper reports on the use of SAM in a financial services firm. Data from completed projects are applied to the model to determine whether SAM is useful as a management tool to create, assess and sustain strategic alignment between information technology and the business. The paper demonstrates that SAM has conceptual and practical value. The paper also proposes a practical framework that allows management, particularly technology management, to determine current alignment levels and to monitor and change future alignment as required. Through the use of this framework, alignment is more likely to be achieved in practice. q 2004 Elsevier B.V. All rights reserved.

Research in Complex Humanitarian Emergencies: The Médecins Sans Frontières/epicentre Experience

The United Nations (UN) defines a complex humanitarian emergency (CHE) as “a humanitarian crisis in a country, region, or society where there is total or considerable breakdown of authority resulting from internal or external conflict and which requires an international response that goes beyond the mandate or capacity of any single and/or ongoing UN country program” [1]. Such emergencies require adapted, focused, and pragmatic field responses to be organized within short time frames, often under difficult accessibility, security, and climate conditions. Over the years, operational efficiency in the field has increased thanks to research carried out during CHEs. Early on following its inception in 1971, the international medical humanitarian organization Médecins Sans Frontières (MSF) conducted its medical missions with enthusiasm but little standardization, focusing more on individual care than on optimized public health approaches. Growing field experience, mainly acquired in refugee camps, rapidly led to the identification of ten major public health priorities for CHEs (Box 1). Critical analysis of data collected by MSF field workers generated questions about the effectiveness of MSF’s operational responses (Box 2). Recognizing the importance of epidemiological surveillance and systematic monitoring of CHE activities, MSF created its own research center, Epicentre, in 1987 with the aim of addressing those questions [2]. Twenty years later, Epicentre has developed into a large team of over 40 professionals in the headquarters in Paris, offices in Geneva and Brussels, and a field station in Mbarara, Uganda. Through partnerships with national and international institutions, universities, and research groups, Epicentre has gained recognition in the field of CHE research and, in 1995, became a World Health Organization (WHO) collaborative center for research in epidemiology and control of emerging diseases. To this day, Epicentre is dedicated to improving field operations in CHEs. In this article, we review Epicentre’s 20 years of experience conducting research during CHEs and show how such research has been critical in improving field response.
The Election Controversy Among Lutherans in the Twentieth Century: An Examination of the Underlying Problems

The Election Controversy among Lutherans in the Twentieth Century: An Exa mination of the Underlying Problems. Author: John M. Brenner The Election Controversy of the nineteenth century re-shaped the face of confessional Lutheranism in America. The Evangelical Lutheran Synodical Conference of North America, the leading voice of confessional Lutheranism in America, bore the brunt of the dispute and ultimately dissolved. This dissertation examines the Election Controv ersy with special attention to the twentieth century attempts to resolve it in order to discover the underlying problems that have prevented the opposing sides from reaching a resolution. The disserta tion is written from the viewpoint of the Wisconsin Synod, one of the synods involved in the controversy but often ignored in the discussion of it. The study is needed because contemporary observ ers do not have a good understanding of confessional Lutheranism and Lutheranism’s historic e mphasis on doctrinal purity. The dissertation demonstrates that the underlying caus es of the controversy and the failures to resolve it were departures from Luther’s approach t theology and from the historic Lutheran stress on doctrine and doctrinal agreement for the expression of churc h fellowship.

Large variation between hospitals in immediate breast reconstruction rates after mastectomy for breast cancer in the Netherlands.

BACKGROUND
The present study aimed to describe the use of immediate breast reconstruction (IBR) after mastectomy for invasive breast cancer and ductal carcinoma in situ (DCIS) in hospitals in the Netherlands and determine whether patient and tumor factors account for the variation.


METHODS
Patients undergoing mastectomy for primary invasive breast cancer or DCIS diagnosed between January 1, 2011 and December 31, 2013 were selected from the NABON Breast Cancer Audit. All the 92 hospitals in the Netherlands were included. The use of IBR in all hospitals was compared using unadjusted and adjusted analyses. Patient and tumor factors were evaluated by univariate and multivariate analyses.


RESULTS
In total, 16,953 patients underwent mastectomy: 15,072 for invasive breast cancer and 1881 for DCIS. Unadjusted analyses revealed considerable variation between hospitals in postmastectomy IBR rates for invasive breast cancer (mean 17%; range 0-64%) and DCIS (mean 42%; range 0-83%). For DCIS, younger age and multifocal disease were factors that significantly increased IBR rates. For patients diagnosed with invasive breast cancer, IBR was more often used in younger patients, multifocal tumors, smaller tumors, tumors with a lower grade, absence of lymph node involvement, ductal carcinomas, or hormone-receptor positive/HER2-positive tumors. After case-mix adjustments for these factors, the variation in the use of IBR between hospitals remained large (0-43% for invasive breast cancer and 0-74% for DCIS).


CONCLUSIONS
A large variation between hospitals was found in postmastectomy IBR rates in the Netherlands for both invasive breast cancer and DCIS even after adjustment for patient and tumor factors.
The psychosocial impact of Klinefelter syndrome and factors influencing quality of life

Purpose: There is considerable information regarding the medical and cognitive aspects of Klinefelter syndrome yet little research regarding its psychosocial impact. This study investigates the personal impact of Klinefelter syndrome and the influence of age at diagnosis, clinical, social, and demographic factors on adult quality of life outcomes.Methods: Men from across Australia, diagnosed with KS at different ages, were recruited through multiple sources. Participants completed a questionnaire assessing subjective well-being, body image, self-esteem, mental health, social support, and general health.Results: Eighty-seven individuals self-completed the questionnaire. All outcomes were much poorer for the study population than for the general male population. Individuals diagnosed later in life reported many of the same symptoms as those diagnosed at younger ages. Employment status, social support, and phenotypic features were the strongest predictors of psychosocial outcomes. Age at diagnosis was not as influential because it did not correlate with phenotypic severity score.Conclusion: This is the first quantitative study to show Klinefelter syndrome has a significant personal impact. Men diagnosed with Klinefelter syndrome later in life reported similar difficulties as those at younger ages, suggesting that they would benefit from early detection and intervention. Understanding factors influencing this can assist in providing adequate services to individuals with Klinefelter syndrome, their partners, families, and the health professionals caring for them.
Fuzzy spatial relation ontology for image interpretation

The semantic interpretation of images can benefit from representations of useful concepts and the links between them as ontologies. In this paper, we propose an ontology of spatial relations, in order to guide image interpretation and the recognition of the structures it contains using structural information on the spatial arrangement of these structures. As an original theoretical contribution, this ontology is then enriched by fuzzy representations of concepts, which define their semantics, and allow establishing the link between these concepts (which are often expressed in linguistic terms) and the information that can be extracted from images. This contributes to reducing the semantic gap and it constitutes a new methodological approach to guide semantic image interpretation. This methodological approach is illustrated on a medical example, dealing with knowledge-based recognition of brain structures in 3D magnetic resonance images using the proposed fuzzy spatial relation ontology. © 2008 Elsevier B.V.

The Intelligent Crude Oil Anti-theft System Based on IoT Under Different Scenarios

Oil theft always results in huge economic loss, human casualties, and extremely environmental pollution especially when the leaks from crude oil pipeline are not detected and repaired timely. In this paper, we focus on how to detect and monitor abnormal noise and vibration beforehand or in real time by the Internet of Things (IoT). Firstly, the diversities of crude oil theft and the difficulties of oil anti-theft are analyzed in China, and the requirement analysis of the IoT application is stated. Secondly, the intelligent antitheft system based on the IoT is planned and designed for crude oil transportation by tank trucks and by oil pipelines according to the current situation in China. Thirdly, the problems of anti-theft system implementation are discussed, and the suggestions and advice are put forward to ensure that the system can be implemented successfully. The intelligent anti-theft system application can not only stop oil theft timely, but also prevent oil mice from stealing crude oil beforehand. © 2016 The Authors. Published by Elsevier B.V.

UML 2001: A Standardization Odyssey

proposing the UML specification for international standardization. It is anticipated that the “fast track” PAS process will complete sometime next year, at which time UML will be formally recognized as an international standard for information technology. The major benefits of international standardization for a specification include wide recognition and acceptance, which typically enlarge the market for products based on it. However, these benefits often demand a high price. Standardization processes are typically formal and protracted, seeking to accommodate a diverse range of technical and business requirements. From a business perspective, the timescales of standards usually conflict with the competitive need to use the latest technology as early as possible. From a technical perspective, the need to achieve consensus encourages “design by committee” processes. In this sort of environment, sound technical tradeoffs are often overridden by inferior political compromises. Too frequently the resulting specifications become bloated with patches in a manner similar to the way laws become fattened with riders in “pork belly” legislation. This article explores how the UML is faring in the international standardization process. It assumes the reader is generally familiar with the use of UML, and instead focuses on the language’s recent and As the UML reaches the ripe age of four, both its proponents and its critics are scanning the recent changes in the UML 1.3 revision.
"Peculiarly happy at taking likenesses": Zoffany & British portraiture

Book synopsis: The 18th-century painter Johan Zoffany (1733–1810) was an astute observer of the many social circles in which he functioned as an artist over the course of his long career. This catalogue investigates his sharp wit, shrewd political appraisal, and perceptive social commentary (including subtle allusions to illicit relationships)—all achieved while presenting his subjects as delightful and sophisticated members of polite society. 
 
A skilled networker, Zoffany established himself at the court of George III and Queen Charlotte soon after his arrival in England from his native Germany. At the same time, he befriended the leading actor David Garrick and through him became the foremost portrayer of Georgian theater. His brilliant effects and deft style were well suited to theatricality of all sorts, enabling him to secure patronage in England and on the continent. Following a prolonged visit to Italy he travelled to India, where he quickly became a popular and established member within the circle of Warren Hastings, the governor-general. Zoffany's Indian paintings are among his most spectacular and allowed him to return to England enriched and warmly welcomed. This volume provides a sparkling overview of his finest works.
An energy-efficient wireless sensor network for precision agriculture

The use of wireless sensor networks is essential to implementation of information and control technologies in application areas such as precision agriculture. We design MAC and Network layers for a wireless sensor network deployed for a precision agriculture application which requires periodic collection of sensor readings from fixed locations in a field. The Physical layer consists of a radio which operates in multiple power levels in the transmit mode and multiple sensitivity levels in the receive mode. The MAC layer is designed to save energy during the wake-up synchronization phase. The network layer is designed to custom fit the needs of the application, namely periodic data collection from fixed locations, and to minimize the energy consumption through balancing the communication load. The design of various protocol layers involves a cross-layer design strategy, taking into consideration the requirements and the characteristics of the application.
The effects of varying acidity on Helicobacter pylori growth and the bactericidal efficacy of ampicillin.

BACKGROUND
Penicillins inhibit cell wall synthesis; therefore, Helicobacter pylori must be dividing for this class of antibiotics to be effective in eradication therapy. Identifying growth responses to varying medium pH may allow design of more effective treatment regimens.


AIM
To determine the effects of acidity on bacterial growth and the bactericidal efficacy of ampicillin.


METHODS
H. pylori were incubated in dialysis chambers suspended in 1.5-L of media at various pHs with 5 mM urea, with or without ampicillin, for 4, 8 or 16 h, thus mimicking unbuffered gastric juice. Changes in gene expression, viability and survival were determined.


RESULTS
At pH 3.0, but not at pH 4.5 or 7.4, there was decreased expression of ~400 genes, including many cell envelope biosynthesis, cell division and penicillin-binding protein genes. Ampicillin was bactericidal at pH 4.5 and 7.4, but not at pH 3.0.


CONCLUSIONS
Ampicillin is bactericidal at pH 4.5 and 7.4, but not at pH 3.0, due to decreased expression of cell envelope and division genes with loss of cell division at pH 3.0. Therefore, at pH 3.0, the likely pH at the gastric surface, the bacteria are nondividing and persist with ampicillin treatment. A more effective inhibitor of acid secretion that maintains gastric pH near neutrality for 24 h/day should enhance the efficacy of amoxicillin, improving triple therapy and likely even allowing dual amoxicillin-based therapy for H. pylori eradication.
