Abstract

Purpose

The development of oil shale has become a popular technique in the energy industry in recent years. Although more research attention has been paid to this topic, there are scanty studies on patent portfolios. This study aims to explore this current mainstream technique and the patent portfolios of oil shale developers and investigates the major assignees at present to find the technical development trend of oil shale as a reference for government, policy makers, investors and industrial strategic development.

Design/methodology/approach

This study applies correspondence analysis and K-means clustering analysis on data mining and probes into the competitive techniques and strategic groups of the main enterprises in the oil shale industry. In addition, by approval dates, this study analyzes technical directions and the development trends of the current main oil shale enterprises.

Findings

The findings show differences in the enterprises regarding technical positions and patent portfolio strategies.

Originality/value

Differential positioning analysis suggests the relative technical advantages of the various enterprises and evaluates the competition among oil shale enterprises.

Abstract

Purpose

In the current knowledge-based economy era, national innovation ability is crucial. Abundant information can be obtained through patent analysis, and such information can help in the formulation of policies and the making of R&D decisions; numerous researchers thus continue to make patent analyses. The quality of patents possessed by a country indicates the level of innovation and technology in the country, and this study aims to assess the quality of patents possessed by various countries.

Design/methodology/approach

In this study, the authors determined patent quality in various countries from the perspective of the reflective measurement model and used a novel method to construct a structural model of patent quality.

Findings

This study discovered that patent family, number of claims, number of international patent classifications, forward citations, nonpatent references and maintenance time are the structural factors that affect patent quality. Forward citations and the number of claims are particularly highly explained by patent quality, which is a latent construct.

Originality/value

The results of this study provide valuable information to the government and help in the assessment of patent quality in various countries. In addition, the assessment model proposed in this study can be used in the investigation of patent quality in academic research and can predict patent quality, which will be of interest to the government and industry.

Abstract

Purpose

This paper tries to find how investors evaluate mutual fund performance, not only based on both quantitative but also qualitative criteria.

Design/methodology/approach

This paper adopts the modified Delphi method and the analytical hierarchy process (AHP) to design an assessment method for evaluating mutual fund performance.

Findings

The most important criteria of mutual fund performance should be “mutual fund style,” following is “market investment environment.” This result indicates investors' focus when they evaluate the mutual fund performance.

Research limitations/implications

The AHP assumes the criteria are independent between each other. However, in many real cases, the criteria to evaluate the funds' performance may not be independent. Therefore, the authors recommend correlation between each criterion can be considered in the future research.

Practical implications

When making investment decisions, investors should be more concentrate on gathering information of mutual fund style. As for mutual fund issuers, they could also leverage these results to communicate with their clients in more efficient way.

Originality/value

This study presents a framework of assessable mutual fund performance where the AHP were employed for finding the both tangible and intangible key criteria of performance evaluation.

Abstract

Purpose

The purpose of this paper is to explore how the nursing division supervisors at hospitals perceive intellectual capital (IC) and identify the relative importance of IC factors.

Design/methodology/approach

Using literature review combined with experts’ viewpoints, IC is divided into four main structures and adopted them as the measurement criteria. A set of criteria that measure the hospital nursing division's IC was established using the Fuzzy Delphi Method, by the expert questionnaire given out to nursing division supervisors at large-scale teaching hospitals.

Findings

The research results will hopefully help the management of medical institutions make decisions and input more resources in the “structural capital” perspective of their respective nursing divisions.

Originality/value

Hospitals in Taiwan may improve in performance and medical services quality.
