A Critical Study Of Organizational Communication And Organizational Communication Theories- A Historical Perspective, Ratnesh Dwivedi Mr

Ratnesh Dwivedi

Organizational Communication is the study that looks at human communication within and outside the organization. Conrad and Poole (1998) break the definition of organizational communication in parts, by first defining communication and then analyses the organization. These researchers define communication as “a process through which people, acting together, create, sustain, and manage meanings through the use of verbal and nonverbal signs and symbols within a particular context” (Conrad and Poole, 1998, p. 5). In the context of this book, Kenyans and their leaders are communicating their views and final decision through the ballot box to elect their third president, during …

A Multi-Platform Application Suite For Enhancing South Asian Language Pedagogy, Tao Bai, Christopher K. Chung, Konstantin Läufer, Daisy Rockwell, George K. Thiruvathukal

George K. Thiruvathukal

This interdisciplinary project explores the potential for handheld/wireless (H/W) technology in the context of language education within and beyond the classroom. Specifically, we have designed and implemented a suite of multi-platform (desktop/laptop, handheld, and browser) applications to enhance the teaching of South Asian languages such as Hindi-Urdu. Such languages are very difficult to learn, let alone write, and H/W devices (with their handwriting/drawing capabilities) can play a significant role in overcoming the learning curve. The initial application suite includes a character/word tracer, a word splitter/joiner, a smart flashcard with audio, contextual augmented stories for reading comprehension, and a poetic metronome. …

Enhancing The Cs Curriculum With With Aspect-Oriented Software Development (Aosd) And Early Experience, Konstantin Läufer, George K. Thiruvathukal, Tzilla Elrad

George K. Thiruvathukal

Aspect-oriented software development (AOSD) is evolving as an important step beyond existing software development approaches such as object-oriented development. An aspect is a module that captures a crosscutting concern, behavior that cuts across different units of abstraction in a software application; expressed as a module, such behavior can be enabled and disabled transparently and non-invasively, without changing the application code itself. Increasing industry demand for expertise in AOSD gives rise to the pedagogical challenge of covering this methodology and its foundations in the computer science curriculum. We present our curricular initiative to incorporate a novel course in AOSD in the …

Public Accountability And Media : Its Success And Failure In Performing The Role As A Force For Public Accountability, Ratnesh Dwivedi Mr

Ratnesh Dwivedi

Media accountability is a phrase that refers to the general (especially western) belief that mass media has to be accountable in the public’s interest - that is, they are expected to behave in certain ways that contribute to the public good. The concept is not clearly defined, and often collides with commercial interests of media owners; legal issues, such as the constitutional right to the freedom of the press in the U.S.; and governmental concerns about public security and order. Several international organizations, like International Freedom of Expression Exchange, Freedom House, International Press Institute, World Press Freedom Committee and the …

Risk-Based Critical Infrastructure Priorities For Emp And Solar Storms, George H. Baker Iii

George H Baker

Two electromagnetic phenomena have the potential to create continental-scale disasters. The first, nuclear electromagnetic pulse (EMP), results from a nuclear detonation high above the tropopause. The second, a major solar storm, or "solar tsunami" occurs naturally when an intense wave of charged particles from the sun perturbs the earth's magnetic field. Both phenomena can debilitate electrical and electronic systems necessary for the operation of infrastructure systems and services. One reason why a U.S. protection program has yet to be initiated is that policy makers continue to wrestle with the question of where to begin, given the Department of Homeland Security’s …

Beyond Multiple Regression: Using Commonality Analysis To Better Understand R2 Results, Russell Warne

Russell T Warne

Multiple regression is one of the most common statistical methods used in quantitative educational research. Despite the versatility and easy interpretability of multiple regression, it has some shortcomings in the detection of suppressor variables and for somewhat arbitrarily assigning values to the structure coefficients of correlated independent variables. Commonality analysis—heretofore rarely used in gifted education research—is a statistical method that partitions the explained variance of a dependent variable into nonoverlapping parts according to the independent variable(s) that are related to each portion. This Methodological Brief includes an example of commonality analysis and equations for researchers who wish to conduct their …

Risk-Based Critical Infrastructure Protection Priorities For Emp And Solar Storms, George H. Baker Iii

George H Baker

The Commission to Assess the Threat to the United States from Electromagnetic Pulse Attack has provided a compelling case for protecting civilian infrastructure against the effects of EMP. As with protecting infrastructure against any hazard, it will be important to take a risk-based priority approach for EMP, recognizing that it is fiscally impracticable to protect everything. In this regard, EMP is particularly challenging in that it interferes with electrical and electronic data, control, transmission, and communication systems organic to nearly all infrastructures in a simultaneous and wide-scale manner. And, for nuclear burst altitudes of 100s of kilometers, the exposed geography …

How To Make Teaching Of Statistics More Effective In Business Schools?, Kuldeep Kumar

Kuldeep Kumar

Statistics is taught in almost all Business Schools as a core course and prerequisite to may advance economics, finance and accountancy courses. However, Statistics has to be taught in a different way in Business Schools as compared to how it is taught in their own statistics department. There should be more emphasis on applications in Business area rather than theory. There has been lot of interest in teaching of statistics in Business schools for a very long time, for example see Cox (1965), Moore (1976) and Love and Hildebrand (2002). This paper discusses author's experience of teaching statistics in an …

The Human Computer Interaction Issues Associated With The Creation Of Personalized Role Playing Simulations, Eileen O'Donnell, Catherine Mulwa, Mary Sharp, Vincent Wade

Eileen O'Donnell

The human computer interaction issues associated with the creation of personalized role playing simulations are discussed in this paper. This paper is aimed at those who are interested in building authoring applications which enable educators to build role playing simulated e-learning resources to use with their students. One of the main issues which have come to our attention is that many learning designers and educators do not understand what exactly it is we are trying to achieve by creating personalized role playing simulations. Also, how to gauge the pedagogic merits which can be achieved by using these e-learning resources. Potential …

Confluence Journal Environmental Studies (CJES), Kogi State University, Nigeria

Proper coordination of transport and public facilities provision is vital to any balanced regional development strategy. The central aim of this study, therefore, is to find out what the relationship is between access to the transport network and the provision of functional indices of facility occurrence towards the distribution of social services in Lagos Island, Nigeria. In particular it seeks to find out areas that have below or above average level of facility occurrences relative to the level of accessibility. However, a pair wise correlation matrix of the eleven (11) variables employed in the index construction was carried out. The …

Emp: A Brief Tutorial, George H. Baker Iii

George H Baker

A nuclear detonation at altitudes from about 30 to 500 kilometers generates a strong electromagnetic pulse (EMP) that propagates to points on the ground within the line-of-sight of the burst. For bursts above 100 kilometers, electronics can be affected over continental scale areas. The EMP induces large voltages and currents in antennas and cables of electronic systems that will upset operation or damage circuit components if protection measures are not present. The article provides a brief tutorial on EMP environments, effects and protection.

High Power Electromagnetic Weapons: A Brief Tutorial, George H. Baker Iii

George H Baker

High power electromagnetic weapons, also referred to as high power radiofrequency (HPRF) weapons, are a type of directed energy weapons. The system effects of high power electromagnetic environments are well recognized by world scientific and military communities. Former CIA Director John Deutch has said that, "the electron is the ultimate precision-guided weapon." In the course of the investigation ofnuclear EMP effects on electronics during the Cold War period, it became evident that garden variety, unprotected electronics would malfunction, in some cases burn out, in the presence of electromagnetic fields in the hundreds to thousands of volts per meter. The EMP …

Urban Climate And Challenges Of Tropical Cities, B E. Omogbai

Confluence Journal Environmental Studies (CJES), Kogi State University, Nigeria

This study examines the nature of urban climate, features and the challenges on the developing tropical cities in the 21st century. It argues that the use of principles of urban climate would help in providing comfortable living conditions and problem immune working environments for the inhabitants of tropical cities. The findings reveal that owing to poor environmental planning, inadequate geotechnical landscape surveys prior to the development of urban infrastructures, and non-adherence to the principles of urban climate, challenges of landscape degradation, excessive flooding of the built infrastructures, heat-island effects, and collapse of buildings have emerged. Suggested measures to avert these …

How Do Environmental And Natural Resource Economics Texts Deal With The Simple Model Of The Intertemporal Allocation Of A Nonrenewable Resource, Robert Main

Robert S. Main

Textbooks in Environmental and Natural Resource Economics invariably deal with the problem of allocating a non-renewable resource over time. The simplest version of that problem is the case of a resource that is to be allocated over two periods. The resource has a constant Marginal Extraction Cost (MEC). Most textbooks treat this case before moving on to more complex and realistic cases. This paper suggests the results that should be emphasized and the method that should be used to arrive at those results. It also points out the possible confusions that should be avoided. Finally, it examines how several well-known …

Vuv Absorption Cross Section Of Benzene, Relevance For Titan’S Atmosphere, F-J. Capalbo, Y. Bénilan, N. Fray, M. Schwell, Et. Es-Sebbar, N. Champion, T. Koskinen, R. Yelle

Dr. Et-touhami Es-sebbar

Saturn's largest satellite, Titan, is the only one in the Solar System known to have a thick N2/CH4, planet like atmosphere. The dissociation of these principal components and the recombination of the products make this atmosphere to be rich in organic compounds of high interest for astrobiology. Solar and stellar occultations observed by the Ultraviolet Imaging Spectrograph (UVIS) on board the Cassini spacecraft can be used to characterize the composition of Titan’s upper atmosphere (400 – 1400 km). The results depend strongly on the knowledge of the molecular absorption cross sections of the atmospheric constituents (Ferradaz et al. 2009). This …
