Abstract

Purpose

Based on the general formula, which depends on the length and difficulty of the test, the number of respondents and the number of ability levels, this study aims to provide a closed formula for the adaptive tests with medium difficulty (probability of solution is p = 1/2) to determine the accuracy of the parameters for each item and in the case of calibrated items, determine the required test length given number of respondents.

Design/methodology/approach

Empirical results have been obtained on computerized or multistage adaptive implementation. Simulation studies and classroom/experimental results show that adaptive tests can measure test subjects’ ability to the same quality over half the test length compared to linear versions. Due to the complexity of the problem, the authors discuss a closed mathematical formula: the relationship between the length of the tests, the difficulty of solving the items, the number of respondents and the levels of ability.

Findings

The authors present a closed formula that provides a lower bound for the minimum test length in the case of adaptive tests. The authors also present example calculations using the formula, based on the assessment framework of some student assessments to show the similarity between the theoretical calculations and the empirical results.

Originality/value

With this formula, we can form a connection between theoretical and simulation results.

Abstract

A large number of potential sites are given and we have to choose k sites in order to set up information centres, where each centre is able to serve a limited number of clients. The price a client pays for accessing a centre is proportional to the distance between the client and the centre. This problem belongs to a class of problems for which most theoretical computer scientists believe that there is no fast algorithm for finding an optimal solution. We therefore look for algorithms that produce an approximate solution. In this paper we present a fast algorithm that chooses k sites and assigns the clients to the centres in such a way that the maximum price a client pays is at most nine times the maximum price in an optimal solution. This algorithm works under the assumption that the number of chosen sites is small in comparison to the number of possible sites.

Abstract

Examines the tenth published year of the ITCRR. Runs the whole gamut of textile innovation, research and testing, some of which investigates hitherto untouched aspects. Subjects discussed include cotton fabric processing, asbestos substitutes, textile adjuncts to cardiovascular surgery, wet textile processes, hand evaluation, nanotechnology, thermoplastic composites, robotic ironing, protective clothing (agricultural and industrial), ecological aspects of fibre properties – to name but a few! There would appear to be no limit to the future potential for textile applications.

Abstract

Purpose

The institutional context in which family firms operate influences their behaviour and performance, yet literature reviews seldom analyse family firms on a regional basis. To fill this gap, this review aims to present research on family entrepreneurship in the transition economies of the Visegrád countries (V4). In this particular group of European economies, the current formal institutions have largely evolved along Western European lines. However, the transformation of informal institutions appears to be still in its infancy.

Design/methodology/approach

In order to identify the most representative authors, the methodologies used, the main research topics and to establish a future research agenda, the authors selected, through a systematic process, 112 papers from the Web of Science up to the year 2022. The authors performed a bibliographic analysis using clustering algorithms, complemented by a traditional literature review.

Findings

The performance of family firms in transition economies has been the subject of very little research. The results allowed the authors to identify four main areas of research: governance, innovation, sustainability, competitive advantage and considering the influence of the region's characteristics on family business behaviour.

Originality/value

Studies from transition economies can contribute to a broader understanding of family firms in terms of the impact of the institutional environment (especially the influence of sociological changes and specific historical experiences of family members) on their long-term planning, socioemotional wealth (SEW) protection and ethics. In light of recent events, research from the region may also contribute to the understanding of how and to what extent “familiness” influences crisis management or socially responsible behaviour in family firms.

Abstract

Looks at the eighth published year of the ITCRR and the research, from far and near, involved in this. Muses on the fact that, though all the usual processes are to the fore, the downside part of the industry is garment making which is the least developed side. Posits that the manufacture of clothing needs to become more technologically advanced as does retailing. Closes by emphasising support for the community in all its efforts.

Abstract

Purpose

This study aims to analyse the efficiency effects of institutional distance on Chinese outward foreign direct investment (FDI) in Africa.

Design/methodology/approach

The study utilised the true fixed-effect stochastic frontier analysis (SFA) model. Data from 2003 to 2016 (14 years) were acquired from 42 targeted African countries, which are included in the analysis.

Findings

The results reveal that FDI flow efficiency can be maximised with a high institutional distance between China and African countries. Contrariwise, comparable institutional distance, measured by the rule of law, regulatory quality and government effectiveness between the host and home countries, reflected a significant positive impact for Chinese outward foreign direct investment (OFDIs), indicating Chinese MNEs can invest directly in a country with comparable institutional characteristics.

Originality/value

There have been limited exceptional studies that assessed the effect of institutional distance between emerging countries. However, none of these studies investigated the effect of institutional distance between China and Africa at a national level. Using the advantage of the SFA model, this study assesses the efficiency effects of institutional distance between the host and home country.

Abstract

Purpose

This qualitative study explores how trailing spouses form their relationships before and after a crisis such as the COVID-19 pandemic and what patterns can be observed. It explores their significant relationships with friends and extended family, focusing on dynamics and change.

Design/methodology/approach

The authors conducted semi-structured interviews with seven trailing spouses in Malaysia: before the pandemic, in the beginning and at the end of the first year of the pandemic. The authors used longitudinal interpretative phenomenological analysis (LIPA).

Findings

Being aware of the limits of resources emerged as a key factor in how trailing spouses develop and maintain relationships with friends and extended family. The fact that the pandemic changed the dynamics of their social networks illuminates how crucial these relationships or their absence are in their adjustment and readjustment process. Children play a significant role in these relationships.

Research limitations/implications

Comparative research into the friendships and relationships of different groups of trailing spouses in various locations could capture more specificity of the relationship dynamics.

Practical implications

The explored patterns can promote a better understanding of the relationship dynamics of trailing spouses' networks, which can, in turn, support and facilitate both adjustment and repatriation processes. They can help explain how and what kind of social networks best support trailing spouse transition during a time of crisis or adjustment. These findings could be incorporated into intercultural training programs.

Originality/value

No current study that the authors know of has explored trailing spouses' relationship dynamics in a longitudinal study before and during a crisis.
