The purpose of this paper is to describe a rapid and robust axisymmetric hybrid algorithm to create dynamic temporal and spatial charge distributions, or charge map, in the simulation of bipolar charge injection using Schottky emission and Fowler-Nordheim tunneling, field-dependent transport, recombination, and bulk and interfacial trapping/de-trapping for layered polymer films spanning the range from initial injection to near breakdown.

This hybrid algorithm uses a source distribution technique based on an axisymmetric boundary integral equation method (BIEM) to solve the Poisson equation and a fourth-order Runge-Kutta (RK4) method with an upwind scheme for time integration. Iterative stability is assured by satisfying the Courant-Friedrichs-Levy (CFL) stability criterion. Dynamic charge mapping is achieved by allowing conducting and insulating boundaries and material interfaces to be intuitively represented by equivalent free and bound charge distributions that collectively satisfy all local and far-field conditions.

Charge packets cause substantial increase of electric stress and could accelerate the breakdown of polymeric capacitors. Conditions for the creation of charge packets are identified and numerically demonstrated for a combination of impulsive step excitation, high charge injection, and discontinuous interface.

Metallized bi-axially oriented polypropylene (BOPP) dielectric thin film capacitor with self-clearing and enhanced current carrying capability offer an inexpensive and lightweight alternative for efficient power conditioning, energy storage, energy conversion, and pulsed power. The originality is the comprehensive physics and multi-dimensional modeling which span the dynamic range from initial injection to near breakdown. This model has been validated against some empirical data and may be used to identify failure mechanisms such as charge packets, gaseous voids, and electroluminescence. The value lies in the use of this model to develop mitigation strategies, including re-designs and materials matching, to avoid these failure mechanisms.

A computer program for the solution of the single carrier semiconductor equations in GaAs has been developed to simulate charge storage and transfer in GaAs charge‐coupled devices. An uncoupled Newton method is used to solve the steady state problem, and a stable, uncoupled method is used for the transient solution. Using transient simulation, the transfer of a charge packet from well to well can be simulated over time. By comparing the size of the charge packet before and after the transfer, information on the charge transfer inefficency can be derived.

Outlines Japan’s journey to third‐generation mobile (3G). Posits a number of factors have been responsible for driving Japan in the direction of 3G. Examines developments in 3G mobile phones and the situation reached in that country. Sums up that there are a number of lessons to be learned from the Japanese experience, notably on market structure.

This case focusses on internal controls necessary to prevent theft of cash collections. Troy Wheeler, assistant dean of the School of Business and Public Policy was asked to write a memorandum to the university’s internal auditor verifying that controls on the cash register in the school were adequate to prevent major theft. Troy wrote the memo, but the request awakened nagging concerns regarding the cash register. The more Troy thought about it, the more concerned he became about the potential for loss. Troy needed to identify the major weaknesses in the existing system and make feasible recommendations to improve control.

This case is based on the author’s personal association with the organization, observation, interviews of key figures in the case, and examination of relevant documents.

This case is appropriate for any graduate or undergraduate accounting class where internal controls are analyzed and documented. The case could be used in courses on internal or external auditing or accounting information systems.

The increasing number of M‐internet subscribers and the fast growing revenue proves the great potential of M‐internet as well as the enormous business opportunity in Korea. The success in this business is dependent on understanding the concerns of customers and identifying the factors that promote the use of M‐internet. Thus, this paper aims to examine the human motivations underlying individual behavioral intention to use M‐internet in Korea.

Employs TAM (technology acceptance model) as the base model and develops a more comprehensive version of TAM to better reflect M‐internet context. The model employs perceived playfulness, contents quality, system quality, internet experience and perceived price level, in addition to perceived usefulness and ease of use. Investigates the causal relationships among the constructs used in this revised TAM and identifies the direct and indirect causal role of the constructs in developing the intention to use M‐internet.

Finds that attitude toward M‐internet is the most significant factor in predicting the behavioral intention to use M‐internet. Also identifies the positive role of the perceived playfulness and the negative role of perceived price level in developing the attitude as well as the intention. The positive causal relationships of “perceived contents quality – perceived usefulness”, “perceived system quality– perceived usefulness” and “internet experience–perceived ease of use” were also witnessed.

Considering the explosive growth of the M‐internet market, well‐established business strategy in M‐internet will deliver great success to the mobile operators. Thus, understanding comprehensive causal relationship among the constructs used in this revised TAM would help managers to better implement the strategic ramifications in promoting M‐internet.

Develops a more comprehensive version of TAM to better reflect M‐internet context in Korea, adding five new constructs and identifies the role of the construct in promoting the use of M‐internet.

In recent years, a number of alternatives for service differentiation and QoS provision have been proposed and standardized in communication networks. In the case of back‐bone networks the DiffServ architecture has prevailed, due to its scalability and deployment feasibility. The provisioning of differentiated services has raised the requirements for interdependent controlled resource allocation and service pricing, with particular needs for pricing mechanisms that preserve the potential and flexibility of the DiffServ framework. At the same time, such mechanisms should reflect resource usage, allocate resources efficiently, reimburse costs or maximize service provision profits and lead customers to requesting services that will maximize their revenue. Presents the key issues involved in the area of pricing DiffServ‐based services and the research work carried out in this field, while at the same time outlining the basic principles that such a pricing infrastructure should obey with respect to the particularities that apply to the case of DiffServ services provision.

A highly significant action taken by the Minister of Agriculture, Fisheries and Food, reported elsewhere in this issue, could well result in important advances in surveillance and probably legislative control over enforcement of certain aspects of EEC legislation in the Member‐states. The Minister has sent an urgent request to the Commission in Brussels to dispatch inspectors to each country, including the United Kingdom, to examine and report on the standards of inspection and hygiene with detailed information on how the EEC Directive on Poultry Meat is being implemented. Information of the method of financing the cost of poultrymeat inspection in each country has ben requested. The comprehensive survey is seen as a common approach in this one field. The Minister requested that the results of the inspectors' reports should be available to him and other Member‐states.

This paper aims to provide an overview of representative multimedia applications in the cultural heritage sector, as well as research results on quality of service (QoS) mechanisms in internet protocol (IP) networks that support such applications.

The paper's approach is a literature review.

Cultural heritage multimedia applications require greater bandwidth capacity, especially where multiple users share the connections. For such applications, scalability and reliability of quality of service depend on packet‐level QoS mechanisms operating in a full end‐to‐end basis.

The paper provides a foundation for future research directions in the professional communication context. For instance, the QoS mechanisms in possible network infrastructures could be used to explore effective multimedia data dissemination across cultural heritage institutions.

The paper provides an overview of which technologies/mechanisms are being used most broadly and which might provide the most potential for cultural heritage institutions managers considering experimenting in the multimedia communications area.

QoS mechanisms that support multimedia applications in the cultural heritage sector need to become well known by cultural heritage institutions managers and professional associations in the fields of libraries, museums and archives. This paper provides a useful overview of the topic.

The total costs of online searching in four hosts — Data‐Star, Dialog, ESA‐IRS, and STN International — were evaluated in a study conducted at the Information Service of the Technical Research Centre of Finland. To make the comparison as comprehensive as possible, six databases were used, all of which are available in the four hosts. The databases were BIOSIS, Chemical Abstracts, COMPENDEX, FSTA, INSPEC, and NTIS. The costs were analysed separately for the searching phase and for the output phase. For the searching phase, the costs were calculated as a function of the connect time. For the output phase, the cost per displayed record were estimated. The estimates were based on measured output time. The telecommunication costs were included, but their share is shown separately. The effect of transmission rate on the connect time and telecommunication costs was also studied by using two different speeds, 1200 baud and 2400 baud. The results of the study are presented in graphs and in tables. The graphs show the conducted values of the various cost components (connect time, output, telecommunication) for the four hosts and six databases. The comparisons of total costs for various types of online searches are presented in tables. At 1200 baud, the most economic searches are usually made in ESA‐IRS. Data‐Star, Dialog and STN are competitive only in very short searches, and at rather high levels of output. At 2400 baud, the competitiveness of Data‐Star, Dialog and STN is much better, especially if a medium‐length format is used for output. Data‐Star and STN which do not have a data network of their own suffer from higher telecommunication costs.

Few will complain that 1974 has not been an eventful year; in a number of significant respects, it has made history. Local Government and National Health Services reorganizations are such events. This is indeed the day of the extra‐large authority, massive monoliths for central administration, metropolitan conurbations for regional control, district councils corresponding to the large authorities of other days; and in a sense, it is not local government any more. As in other fields, the “big batallions” acquire greater collective power than the total sum of the smaller units, can wield it more effectively, even ruthlessly, but rarely appearing to take into account the masses of little people, the quiet people, who cannot make themselves heard. As expected, new names of authorities are replacing the old; new titles for departments and officers, ambitious and high‐sounding; a little grandiose for the tongues of ordinary folk. Another history‐making event of 1974, in the nature of a departmental transfer but highly significant for the course of future events as far as work in the field is concerned, was handing over of the personal health services—health of expectant mothers, babies, children, domiciliary midwifery, the school health services and their mainly medical and nursing personnel—from local health authorities to the newly created area health authorities. The public health departments over fifty years and more had created them, built them up into the highly efficient services they are. If anything can be learned from the past, new authorities are always more expensive than those they replace; they spend freely and are lavish with their accommodation and furnishings. In their first few months of existence, the new bodies have proved they are no exception. News of their meetings and activities in many areas is now scanty; even local newspapers which usually thrive on Council news—or quarrels—seem to have been caught on the wrong foot, especially in the small towns now merged into larger units. The public are relatively uninformed, but this doubtless will soon be rectified.
