We analyze and assess new evidence on employment dynamics from a new data source – the National Establishment Time Series (NETS). The NETS offers advantages over existing data sources for studying employment dynamics, including tracking business establishment relocations that can contribute to job creation or destruction on a regional level. Our primary purpose in this paper is to assess the reliability of the NETS data along a number of dimensions, and we conclude that it is a reliable data source although not without limitations. We also illustrate the usefulness of the NETS data by reporting, for California, a full decomposition of employment change into its six constituent processes, including job creation and destruction stemming from business relocation, which has figured prominently in policy debates but on which there has been no systematic evidence.

Since the execution of National Health Insurance system in Taiwan, the competition of medical industry is becoming more and more severe. The ways the hospital operate knowledge management (KM) concept, combine current human resources and professional knowledge by information techniques and upgrade the competitiveness through reinvention of organizational culture have become the important issues. This research is based on the relationship between KM and organizational operation, integrates the characteristic of medical institutions and framework of medical knowledge cycle and starts the research subject by questionnaires from three dimensions: current situation of KM construction in medical organizations, executive effect of KM activities and the challenges faced by KM; subsequently, from qualitative interview, this research attempts to understand how a medical organization executes and adjusts in the consideration of theory and reality as well as quality and costs when actually operates the organization. This research accesses to KM system application of medical institutions and the empirical executive benefits and difficulties through questionnaires. The research results are as follows: (1) having initial understanding toward current KM establishment of medical institutions; (2) confirming the most important items of KM establishment of medical organizations; (3) understanding the most difficulty which the medical organizations encounter when executing KM; (4) establishing medical knowledge cycle figure of the hospitals receiving interviews. Through case interview, this research profoundly accessed to the actual operation of KM application of medical organizations. The target hospitals intended to try many medical KM measures; however, during to complicated hospital organizations and cultural characteristics, the promotion was not successful and the results were not apparent. The most difficulty was to change the employees’ behavior. The targets believed that only the continuous promotion of KM can allow it to be an important aspect of organizational culture and the competitiveness could constant be upgraded.

Between submission of a resume and actual employment lies the job interview. What the applicant knows about the company may produce a successful interview and result in employment. Researching a company prior to the interview provides the confidence to ask pertinent questions and to relate job skills to company needs. Skilled interviewers can detect familiarity with their operation and are favorably impressed.

This article describes an important project in the history of preservation of Egypt's culture heritage. Initiated by the Egyptian Ministry of Culture and executed by the Cabinet Information and Decision Support Center (IDSC), the project involves the Cairo Egyptian museum that contains the world largest collection of ancient Egyptian antiquities (160,000 objects). A major problem in the museum is the lack of a standardised approach for registration, resulting in a variety of unrelated registration schemes and the non‐existence of efficient tools for information dissemination. This project aims to resolve these problems. A team of Egyptologists, museum curators and system analysts, designers and developers defined the basis for work and specified project challenges which included the indexing of all museum objects ensuring cross‐referencing between already used registration schemes. The result has involved the use of multimedia computer technology to establish a complete database of museum objects (text, image and sound) and various cultural products, in addition to the establishment of required procedures and standards to organise the internal museum workflow and the provision of training programmes for staff. The outcome of the project is expected to be profound in enabling researchers and curators to have instant access to any object in the museum and providing the museum's visitors and public with a wealth of information about ancient Egypt.

Up until the late eighties, there were few information systems in Spanish universities that offered the user online access to databases. Reasons for this were the high cost of the telecommunications and the lack of a sufficiently developed infrastructure. In some cases, the personnel in charge of these systems and, above all, potential users were not acquainted with the services of companies like Red INCA, about which more will be mentioned later.

To solve the problem that the traditional received signal strength indicator real-time location method does not test the attenuation characteristics of the electromagnetic wave transmission in the location area, which cannot guarantee the accuracy of the location, resulting in a large location error.

At present, the compressed sensing (CS) reconstruction algorithm can be roughly divided into the following two categories (Zhouzhou and Fubao, 2014; Lagunas et al., 2016): one is the greedy iterative algorithm proposed for combinatorial optimization problems, which includes matching pursuit algorithm (MP), positive cross matching tracking algorithm (OMP), greedy matching tracking algorithm, segmented orthogonal matching tracking algorithm (StOMP) and so on. The second kind is the convex optimization algorithm, which also called the optimization approximation method. The common method is the basic tracking algorithm, which uses the norm instead of the norm to solve the optimization problem. In this paper, based on the piecewise orthogonal MP algorithm, the improved StOMP reconstruction algorithm is obtained.

In this paper, the MP algorithm (OMP), the StOMP and the improved StOMP algorithm are used as simulation reconstruction algorithms to achieve the comparison of location performance. It can be seen that the estimated position of the target is very close to the original position of the target. It is concluded that the CS grid-based target stepwise location method in underground tunnel can accurately locate the target in such specific region.

In this paper, the offline fingerprint database in offline phase of location method is established and the measurement of the electromagnetic noise distribution in different localization areas is considered. Furthermore, the offline phase shares the work of the location process, which greatly reduces the algorithm complexity of the online phase location process and the power consumption of the reference node, meanwhile is easy to implement under the same conditions, as well as conforms to the location environment.

While the strategic management literature suggests that related diversification is superior to unrelated diversification, there is little evidence that acquirers benefit from pursuing related targets. We argue that the empirical literature is plagued by poor measures of relatedness. Moreover, many empirical studies do not control adequately for the characteristics of the market for corporate control. We argue that not only value creation, but also value appropriation, depend on the relatedness of acquirer and target. Using an improved measure of relatedness, we provide empirical evidence that acquirer returns are positively and significantly correlated with relatedness.

A broad look at geodemographics is presented. The emergence over the last decade of this method of segmenting consumer markets is outlined and probable developments in the 1990s are considered. The lexicon associated with diffusion theory and with the product life cycle is used to give some structure. Information has been synthesised from desk research.
