...Project Part 2 Student SSCP® Domain Research Paper NT2580 Introduction to Information Security May 20, 2013 Security Operations means the process of identifying critical information and subsequently analyzing friendly actions attendant to military operations and other activities to: a. identify those actions that can be observed by adversary intelligence systems; b. determine indicators that hostile intelligence systems might obtain that could be interpreted or pieced together to derive critical information in time to be useful to adversaries; and c. select and execute measures that eliminate or reduce to an acceptable level the vulnerabilities of friendly actions to adversary exploitation. [1] The need to connect and collaborate with partners, suppliers, customers, and employees anytime and anywhere has increased the difficulty of managing network and systems security. Organizations are challenged with the difficult and overwhelming task of securing and managing network systems, and keeping their desktops and servers up to date. Organizations want easy and efficient ways to maintain network security, manage updates, and, at the same time, reduce total costs for security management.

...The Ontology problem in eCommerce applications Rasheed M. Al-Zahrani Information Systems Dept., KSU PO Box 51178, Riyadh, 11543 rasheed@ccis.ksu.edu.sa Abstract Originating in AI semantic networks, ontologies are becoming an essential component of many modern systems. An ontology is a set of specifications, relationships and constraints that describe a certain domain. These specifications capture the concepts pertaining to the domain. Research in this domain is now witnessing intensive efforts due to the growth and success of distributed computing systems in real world applications such as eCommerce, eHealth, eLearning and other eServices. Though at the core of modern distributed technologies, such as multi-agent systems, the ontology issue has sometimes been considered secondary and related issues are underestimated. In this paper, we attempt to address the ontology issue in modern distributed services, and the various problems to be investigated, with special emphasis on eCommerce systems. Our paper illustrates how the semantic-web initiative integrates with ontology. It critically appraises existing solutions, and offers ideas for tackling major ontological issues in eServices. 1. Introduction Distributed systems is the future computing model. This fact is proved by the success of the client-server model and the recent extensions to that model. Maturity of cheap PC, networking and communication technologies contributed to the wide spread adoption of this model. The......

Bloom's Taxonomy of Education

...policy and practice in the history of education. Bloom’s research directed the advancement of many educational programs and provided tools for educator to help students learn. His research on education was conducted from 1940 to 1959 and focused on the relationships between methods of instruction, educational outcomes and measurement of those outcomes. Bloom’s wrote his first book in 1950 which led to the work , the “Taxonomy of Educational Objectives.” His most distinguished contribution to teaching and learning was developing a theory for teachers to provide correct instruction for their students. The revised Bloom’s Taxonomy is used as a framework for continuing education . The purpose of continuing education is to improve nurses’ skills to provide quality patient care. Nurses need to transfer her knowledge from continuing education to everyday practice. Educators can aid the process or transferring knowledge but not to acquire instructional outline. The revised Bloom’s taxonomy incorporates instructional outline into the taxonomy plan to support transfer of knowledge and helps educators to create correct instruction. The application of the research conducted on Bloom’s taxonomy on nursing education provides guidelines to teach , organize lesson plan, assess the strategies in teaching and to evaluate the strategies of teaching. The application of the research is also used to create learning objectives and......

Puberty

...notable for rapid transformation across a multitude of domains. Research suggests that an earlier rate of pubertal maturation in girls correlates with a number of detrimental outcomes compared with on-time or later maturation. The present review synthesizes the research on negative psychological sequelae of early pubertal timing in adolescent girls. Emphasis is on three theoretical perspectives by which precocious development is believed to affect the emergence of adverse outcomes: biological, psychosocial, and selection effects. Consequences of early pubertal timing As a developmental milestone, puberty is notable for its rapid and near-simultaneous transformation across biological, social, and psychological domains. As physical appearance matures, individuals must navigate changing social norms and expectations. This often necessitates a confrontation and, perhaps, reorganization of identity and self-perception. Aberrance in maturational timing seems to increase risk for emotional and behavioral problems during adolescence and early adulthood (Peterson & Taylor, 1980). In particular, girls who mature earlier than their peers seem to find pubertal adjustment especially challenging and are more likely to experience detrimental sequelae (e.g., Caspi & Moffitt, 1991; Ge, Conger & Elder, 1996). Just as puberty itself is multiply determined, the negative outcomes associated with early pubertal timing span multiple domains. These include psychological, medical, sexual, social,......

June Maker, The University of Arizona, USA creativity, intelligence, and problem solving: a defmition and design for cross-cultural research and measurement related to giftedness Abstract A new definition of giftedness is proposed based on a review of the constructs of intelligence, creativity, and problem solving. A research design employed in a series of studi~s of giftedness in children and adults is presented, along w1th a summary of important results. Finally, implications of the design for both research and practice are outlined. Intelligence A central concept in many theories and definitions of intelligence is solving problems or adaptation to one's environment. Although the phrase "problem solving" is not always found, the concept of "adaptation" or "ability to adapt", a central concept in many definitions (Binet & Simon, 1909 (cited in Terman, 1916); Boynton, 1933; Colvin, 1921; French, 1962; Piaget, 1981; Pintner, 1921; Stern, 1914; Wechsler, 1941 ), implies that individuals encounter situations (problems) to which they must devise ways of reacting. Thus, they are solving problems. Later theorists and researchers revised these general concepts of "adaptation" by adding the idea of adapting to the cultural as well as the biological environment (Laboratory of Comparative Human Cognition, 1982_; Goodnow, 1976; Charlesworth, 1976; Olson, 1976;......

Webometrics Rating Improvement as a Marketing Strategy

...University. When a prospect has several choices of Universities providing the same area of study, rating and ranking would come into consideration as the final – if not, an assessed weight in the decision making. Rating and ranking also shows the performance indicator and also shows how prestigious the University is. Through Webometrics, prospects can see the ranking of a University either regionally or internationally based on their rating, and the rating and ranking are updated periodically. Many Universities adopted this rating and ranking system on their own website as their marketing strategy to show that they are better than competitor Universities and the use of Webometrics can be analysed as it displays the University's prestige. This paper will discuss the us of Webometrics as marketing strategy by improving the University's rating and ranking in Webometrics. keyword(s): Webometrics, University rating, marketing strategy, web impact.

Emerging Economies

...Economies: Where Are We Today and Where Should the Research Go in the Future Garry D. Bruton David Ahlstrom Krzysztof Obloj Emerging economies are characterized by an increasing market orientation and an expanding economic foundation. The success of many of these economies is such that they are rapidly becoming major economic forces in the world. Entrepreneurship plays a key role in this economic development. Yet to date, little is known about entrepreneurship in emerging economies. This introductory article to the special issue on entrepreneurship in emerging economies examines the literature that exists to date in this important domain. It then reviews the research that was generated as part of this special issue on this topic. The article concludes with a discussion of the critical future research needs in this area. Introduction The quantity and quality of entrepreneurship research has increased dramatically over the last 15 years. Today, entrepreneurship research is some of the most widely cited in the management discipline, with leading journals dedicated to its study and well-recognized conferences supporting its development. The methods employed and the theory foundations used in entrepreneurship today are consistent with mainstream management research. However, entrepreneurship research can still be critiqued as almost exclusively focused on North American and European research sites. The exploration of domains outside of these two developed economic regions......

Blooms Research and Response

...Bloom’s Research and Response Ralph Guzman NUR/427 June 1, 2012 Professor Smith Bloom’s Research and Response Teaching is something that goes hand-in-hand with nursing. As the teaching role for the Registered Nurse (RN) expands so must the nurse’s teaching skills through continuing education. Because of the diversity of patient population, hospitals and public heath settings the RN should be well prepared to effectively teach patients from all walks of life ie., education, age, culture, religion, etcetera (Crosby, 1977). This essay will go over Bloom’s taxonomy of education and its use in nursing education, the applications of the nursing research conducted on nursing education and will touch on the three domains outlined in Bloom’s taxonomy. In 1956 Benjamin Bloom along with educators from the University of Chicago developed Bloom’s taxonomy of educational objectives. There are three domains in Blooms taxonomy: cognitive, affective and psychomotor. Cognitive : In the cognitive domain learners , which for the purpose of this paper would be a patient, patients would be expected to retrieve information from long-term memory such as knowing what medications are used for and what the side effects might be for that specific medication. After being taught, patients would be expected to be able to verbalize the meaning of oral , graphic or written information; such as being able to verbalize how to recognize the signs and symptoms...

Research

...composed of students, confronted with an integrated, research-based teaching and learning design; the second sample is composed of students, exposed to classic service courses in statistics and research methods. Results reveal that motivations significantly affect Critical Thinking and Self-Regulation and that motivations and attitudes affect learning processes and achievement in their own characteristic way. Moreover the crucial role of an integrated teaching and learning design as a significant contributor to optimal motivations, more favourable attitudes and more adequate learning strategies for studying statistics and research methods has been endorsed. BACKGROUND Most studies concerning statistics (service) courses in the social sciences focus on attitudes and achievement. However, in the domain of educational psychology particularly motivations are regarded as crucial contributors to the learning process (Pintrich and Schunk, 2002). In the domain of statistics education studies generally focus on attitudes, based on empirically proven relations with achievement, disregarding or neglecting motives and learning strategies. Nevertheless, Critical Thinking and Meta-Cognition are recognized as essential learning strategies for the construction of statistical literacy and statistical reasoning (Pfannkuch, 1999; Reading, 1996; Watson and Callingham, 2003). Based on an extensive literature study in the domain of education, psychology and statistics we decided......
