Abstract

Purpose

The purpose of this paper is to propose the numerical pulse test for the parameter estimation of the synchronous machine models.

Design/methodology/approach

In order to generate data for the parameter estimation, the numerical pulse test was utilized. This test was implemented within the two‐dimensional finite element analysis (FEA). From the test data, the parameters of the equivalent circuit model were estimated. The differential evolution algorithm was used to minimize the cost function.

Findings

The equivalent circuit model with the estimated values of the parameters matches well with the data generated by the FEA. Thus, the equivalent circuit model with the parameters estimated represents the behavior of the machine accurately.

Originality/value

Previously, the numerical pulse test for synchronous machines has not been introduced. The numerical pulse test takes the real operation point of the machine into account. In the test, phenomena like the changing permeability distribution and the eddy‐currents in the damper bars (windings) are considered unlike in the standardized standstill frequency response test.

Abstract

Purpose

The purpose of this paper is to study what extent readers’ socio-demographic characteristics, literary preferences and search behavior predict success in fiction search in library catalogs.

Design/methodology/approach

In total, 80 readers searched for interesting novels in four differing search tasks. Their search actions were recorded with a Morae Recorder. Pre- and post-questionnaires elicited information about their background, literary preferences and search experience. Readers’ literary preferences were grouped into four orientations by a factor analysis. Linear regression analysis was applied for predicting search success as measured by books’ interest scores.

Findings

Most literary orientations contributed to search success, but in differing search tasks. The role of result examination was greater compared to querying in contributing search success almost in each task. The proportion of variance explained in books’ interest scores varied between 5 (open-ended browsing) and 50 percent (analogy search).

Research limitations/implications

The distribution of participants was biased toward females, and the results are aggregated within search session, both reducing the variation of the phenomenon observed.

Originality/value

This study is one of the first to explore how readers’ literary preferences and searching are associated with finding interesting novels, i.e. search success, in library catalogs. The results expand and support the findings in Mikkonen and Vakkari (2017) concerning associations between reader characteristics and fiction search success.

Abstract

Purpose

The purpose of this paper is to investigate fiction readers’ interest criteria when selecting novels in library catalogs for various search tasks.

Design/methodology/approach

The data of the book selection behavior from 80 genuine fiction readers were collected using recorded interviews and conversations. The data were qualitatively analyzed. Reuter’s categorization of the components of aesthetic relevance has contributed to the construction of interest dimensions.

Findings

A five-dimension categorization of interest criteria is presented based on fiction readers’ interpretations of the influential factors in fiction book selection in different search tasks. The findings revealed that readers apply the identified interest criteria in a flexible and multiphase way depending to the search task and the system used. The findings showed a context-related pattern in readers’ fiction book selections. A combination of readers’ search capacities, “behind the eyes” knowledge, affective factors and a well-functioning interaction with a system used results in a successful book selection.

Originality/value

A five-dimension categorization of adult fiction readers’ interest criteria was created based on their search behaviors in library catalogs. The results provide a systematic step toward a comprehensive understanding of readers’ fiction book selection in digital environments.

Abstract

Purpose

The entire sector of railway transport is in a state of flux in Europe as deregulation and structural changes are affecting the traditional transport mode. Even though the aim has been to increase railway freight competition, markets have changed only slightly, and the market shares of incumbent railway companies are remaining high. Some EU countries have not attracted any new entrants, which is also the current situation in Finland. This paper aims to assess how the Finnish railway freight competition develops and to analyze different views on railway transport policy.

Design/methodology/approach

This research work analyses a Delphi questionnaire directed at 52 Finnish experts in this branch. Responses on the questionnaire were gathered during year 2005 (competition in Finland in railway freight started 2007) within two rounds with appropriate amount of response rate. Respondents were from the public and private sectors, actors working closely with railway transports and logistics. With an expert profiling matrix, three different railway transport policy viewpoint groups are identified, and character descriptions for these are constructed.

Findings

Based on a qualitative expert profiling analysis, it is argued that there exist three different argument types in Finnish railway transport policy. The authors have constructed character descriptions for each group based on material collected by the Delphi technique. They conclude that the policy definitions have followed the views of the moderate group and the realization of the deregulation process has been slow, even though a great amount of competition was expected.

Research limitations/implications

The research work is limited to the Finnish railway freight transport market, where development of competition on rails has been sluggish. To further confirm the used methodology, and the identified railway freight competition policy group types, the research work should be repeated in some other country, and particularly in an environment where competition has shown activity immediately after deregulation.

Originality/value

The research represents methodology to foresee the future development of deregulated industries, and especially in the transportation sector. The paper's approach can be used to divide stakeholders into groups and to make policy analysis. The problem with to‐be‐deregulated industry is often lack of competition, new actors and governmental actions, and therefore the used Delphi technique offers potential to gather empirical material before any activity has actually started in the observed industry.

Abstract

Purpose

Evidence suggests that a growing number of consumers across the world are becoming more environmentally responsible in terms of their personal habits and lifestyles. In this paper, the authors aim to use both parametric and non-parametric econometric models to estimate Kuwaiti consumers’ willingness to pay (WTP) for environmental protection in Failaka island.

Design/methodology/approach

Contingent valuation methods based on log-logistic and log-normal regression models revealed that consumers in Kuwait are willing to pay a price premium of approximately 40 Kuwaiti dinars for environmental protection in Failaka island based on the double-bound dichotomous choice model.

Findings

Socio-economic variables have no significant influence on the respondent’s WTP. As expected income has a positive relationship with WTP and bid price has negative relationship with WTP to protect the environment in Failaka island.

Originality/value

This study highlight the fact that understanding consumers’ environmental-friendly behaviors may play an important role in formulating environmental policy changes to face complex problems as diverse as environmental pollution or environmental degradation.

Abstract

Purpose

This study aims to increase knowledge of the ability of nutrition labels to guide consumer choices in real-life environments.

Design/methodology/approach

Food consumption and plate waste data were collected from two self-service restaurants (SSR) with different customer groups over six observation days: three control and three intervention (with nutrition labelling) periods. Study Group 1 consisted of vocational school students, mostly late adolescents (N = 1,710), and Group 2 consisted of spa hotel customers, mostly elderly (N = 1,807). In the experimental restaurants, the same food was served to the buffets during the control and intervention periods.

Findings

The nutrition label in the lunch buffet guides customers to eat fewer main foods and salads and to select healthier choices. Increased consumption of taste enhancers (salt and ketchup) was observed in the study restaurants after nutritional labelling. Nutrition labelling was associated with a reduction in plate waste among the elderly, whereas the opposite was observed among adolescents.

Originality/value

The results provide public policymakers and marketers with a better understanding of the effects of nutrition labelling on consumer behaviour. Future studies should further evaluate the effects of nutrition labelling on the overall quality of customer diets and the complex environmental, social, and psychological factors affecting food choices and plate waste accumulation in various study groups.

Abstract

Interest in the field of entrepreneurship has significantly increased among academics, practitioners and government officials in the past decade both in the USA and in Europe. The increased interest is reflected in the increased number of courses, majors and minors at colleges and universities throughout the world; the increased number of endowed chairs; the increased number of journals in the field; the increased coverage of the field by the media; and the increased interest in the provision of government support. In light of this significant increased interest, it is important to understand the state of research in the field in Europe in the last few years, the focus of this article.
