Abstract

Purpose

Traditional crime linkage studies on serial sexual assaults have relied predominantly on a binary crime linkage approach that has yielded successful results in terms of linkage accuracy. Such an approach is a coarse reflection of reality by focussing mainly on the outcome of an offence, neglecting the forceful differences due to the intricate offender-victim interaction. Only few researchers have examined sexual assaults through the lens of a sequence analysis framework. This paper aims to present the first empirical test of offence sequence-based crime linkage, moving beyond exploratory analyses.

Design/methodology/approach

Offence accounts from 90 serial sexual assault and rape victims from the UK were analysed and sequentially coded. Sequence analysis allowed to compare all offences combinations regarding their underlying sequence of events. The resulting comparison was transformed and plotted in two-dimensional space by multidimensional scaling analysis for a visual inspection of linkage potential. The transformed proximities of all offences were used as predictors in a receiver operating characteristic analysis to actually test their discriminatory accuracy for crime linkage purpose.

Findings

Sequence analysis shows significant discriminatory accuracy for crime linkage purpose. However, the method does perform less well than previous binary crime linkage studies.

Research limitations/implications

Several limitations due to the nature of the data will be discussed.

Practical implications

The practical limitations are as follows: the study is a potential practical value for crime analysts; it is a complimentary methodology for statistical crime linkage packages; it requires automated coding to be useful; and it is very dependent on crime recoding standards.

Originality/value

The exploratory part of this study has been published in a book chapter in 2015. However, to the best of the authors’ knowledge, the succinct test of crime linkage accuracy is the first of its kind.

This study quantifies empirically the induced impact of income distribution and consumption expenditure on the structures of agriculture production of Nigerian economy.

Abstract

Purpose

This study quantifies empirically the induced impact of income distribution and consumption expenditure on the structures of agriculture production of Nigerian economy.

Design/methodology/approach

The study calibrates an extended input-output model on a social accounting matrix (SAM) for Nigeria for the year 2010. Moreover, the study conducts a dispersion analysis to identify the key agriculture sectors/subsectors both in exogenous and endogenous setup.

Findings

This study presents an empirical analysis of propagation in the structure of production particularly in the structure of agriculture sector. It combines the aggregate and the disaggregated levels of analysis and identifies the key sectors/subsectors both in the exogenous and endogenous setup. The comparison of both findings confirms that the composition of income distribution and consumption expenditure significantly influences the composition and the aggregated and disaggregated order of structure of agriculture production.

Originality/value

Knowledge of interindustry connections is vital in policy implications since the policy makers prefer strongly interconnected sectors to the sectors with poor industry linkages. These connections are estimated as forward and backward linkages, which provide indices to set the criteria for key sectors identification. This study presents an empirical analysis of propagation in the structure of production particularly in the structure of agriculture sector. It combines the aggregate and the disaggregated levels of analysis and identifies the key sectors/subsectors both in the exogenous and endogenous setup.

Abstract

Purpose

This paper aims to explore whether increasing Chinese foreign direct investment (FDI) is associated with rising contributions of local industry in African countries connected to the Belt and Road Initiative (BRI). The existence of cooperative industry linkages between Chinese investments and local businesses is a necessary condition for achieving the mutual benefits asserted by the BRI.

Design/methodology/approach

Under growing FDI, the authors framed increasing local industry contribution as indicative of existing industry linkages. Using principal component analysis and multiple regression on collated country-level data, the authors examined relationships between key industry output variables and several independent variables representing Chinese investment and economic activity in a contiguous three-country region, over two investment periods.

Findings

Increasing Chinese FDI was associated with positive economic outcomes including decreasing unemployment; however, it did not appear to support local industry participation. The authors identified a “China effect” that hampered industry contribution to gross domestic product. The authors found that attempting to counterbalance this effect through direct exports to China was not strategically sound. Similarly, export-focused clusters in special zones may not foster industry linkages if they result in isolationism. Rather, host countries have an opportunity to enhance local industry contribution through leveraging interconnectivity factors under increasing FDI.

Research limitations/implications

Small sample size of the study has implications for the predictive power of the model and for the complete explanation all the emerging findings. However, the authors presented compelling arguments for selecting the specific three countries. By conducting robustness checks on a separate region, findings of this study were substantially corroborated.

Practical implications

Instead of exporting directly to China as a way to mitigate local industry contraction, host countries need to thoughtfully pursue opportunities that present the greatest value-added export advantages. Proposed Chinese-funded infrastructure projects must be negotiated with a goal to strategically reduce interconnectivity barriers and achieve broader logistics improvements in the host countries.

Social implications

The study provides a tool for proponents of local industry growth to present clearer frameworks in their advocacy. The social tensions around Chinese dominance in the host countries can be reduced by understanding and pursuing levers that enhance industry contribution in those contexts.

Originality/value

This study takes a different approach to examining the professed win-win proposition of the BRI in Africa. It uncovers important effects of increasing Chinese FDI and addresses viable host country responses, including a clear pathway for forging the cooperative industry linkages needed for inclusive growth and sustainable development.

Abstract

Purpose

The purpose of the paper is to investigate the nature of linkages between characteristics of a service and customer consequences and elicit the types of such linkages.

Design/methodology/approach

The paper builds on current research on linkages and customer consequences within the means‐end approach and on a qualitative case study in the context of website use in business‐to‐business relationships.

Findings

The paper introduces six types of linkages between characteristics of a service and customer consequences: common and unique, conflicting and non‐conflicting, and homogenous and heterogeneous linkages.

Practical implications

The paper portrays four cases of implications of the linkages for simplicity and homogeneity of the design of services and of their marketing strategies.

Originality/value

The ways in which characteristics of a service are linked with customer consequences of an engagement with the service are of crucial importance in marketing. Despite the importance, research on linkages is scarce. By considering currently neglected aspects such as different units of analysis, different relationships between characteristics and customer consequences, and diversity in characteristics and consequences, the paper introduces new types of linkages. It also depicts the relevance of the knowledge of the linkages for portraying customer value fully.

Abstract

Purpose

The Violent Crime Linkage Analysis System (ViCLAS) is a computerised database which is used by law enforcement in several countries to find potential links between serial violent crimes. In 2012, Bennell, Snook, MacDonald, House and Taylor identified a number of assumptions that must be valid for these computerised systems to be effective.

Design/methodology/approach

This paper revisits and expands on these assumptions with specific reference to the use of ViCLAS, looking at research that has been conducted since this 2012 review and outlining where research is still outstanding.

Findings

The importance of evaluating ViCLAS is highlighted in this paper.

Practical implications

Particularly, the research agenda highlights how the practice of comparative case analysis when using ViCLAS could be improved.

Originality/value

To the best of the authors’ knowledge, this is the first review of the research dedicated specifically to the evaluation of ViCLAS.

Abstract

Purpose

The purpose of this paper is to investigate the linkage between self‐managing team (SMT) member perceptions of collective efficacy and customer‐perceived service quality, and the most cost‐efficient way to reliably assess collective efficacy and customer‐perceived service quality, using generalizability theory (G‐theory).

Design/methodology/approach

Longitudinal design; employee and customer survey data from 52 teams of a major financial services institution were collected at two points in time.

Findings

First of all, results of OLS regression analysis show a positive effect of collective efficacy on customer‐perceived service quality. In addition, taking a G‐theory approach, the results indicate that collective efficacy possesses a higher psychometric quality than customer‐perceived service quality and that the costs of reliably comparing SMTs on collective efficacy are considerably lower compared to customer‐perceived service quality. Finally, for both constructs, the results reveal subtle but relevant differences in psychometric quality and costs of data collection across different types of service (routine versus non‐routine) settings.

Practical implications

To begin with, as a linkage construct, collective efficacy provides managers a mechanism for team intervention by means of task‐focused team building, role‐play exercises, and using feedback to increase service employee confidence. Secondly, when deciding to use survey data as one means to compare performance of organizational units, managers should first determine to what extent the distinct measurement design facets (e.g. items, persons, and occasions) account for variance in measures and sample correspondingly to save money on data collection. In doing so, they should explicitly take into account the type of service context and type of respondent.

Originality/value

This study identifies collective efficacy and customer‐perceived service quality as a set of service SMT performance measures that meaningfully connects employee and customer perceptions at the group level. Secondly, a G‐theory approach was used to assess the psychometric quality of these two measures and how data collection costs can be minimized to achieve a desired level of generalizability.

Abstract

Purpose

The paper aims to propose and compare two new structures of a three-phase wound field salient rotor (WFSR) switched-flux motor (SFM) with 24 stator slots and 10 or 14 rotor poles, respectively, for high-speed operation.

Design/methodology/approach

The paper outlines the motor general construction and design concept of proposed machines. Flux linkage, average torque, rotor mechanical strength and torque–speed characteristics of both machines were analyzed and compared by two-dimensional finite element analysis (2D-FEA). Deterministic optimization method was adopted to enhance the characteristics of 24Slot-10Pole WFSR SFM.

Findings

The paper provides simulation results and discusses how 24Slot-10Pole WFSR SFM structure is superior to the 24Slot-14Pole in the aspects of flux linkage, average torque and power. It further concludes that the optimized design of 24Slot-10P has achieved 58 and 72 per cent higher average torque and power compared to initial design, as well as high average torque and power compared to 24Slot-14P design.

Originality value

Optimized structure of the 24Slot-10Pole WFSR SFM with non-overlapping windings has been proposed.

Abstract

Purpose

The purpose of this study is to explore why A‐list bloggers are continuously popular and what benefits they may obtain from becoming A‐list bloggers.

Design/methodology/approach

This work compared the varying popularity ranking list at two stages of Wretch, the biggest blog platform in Taiwan, and selected 44 continuously popular A‐list bloggers as research subjects. The research used online ethnographic methods, social network analysis, and text analysis to analyse collected data, including personal blog homepages, profile pages, blogrolls, blog posts, and audience responses to 44 continuously popular A‐list bloggers.

Findings

The results reveal that, on average, A‐list bloggers publish several articles weekly. Each article draws many responses and quotations; however only a few audience members continuously respond to these articles. The social network analysis and the online ethnographic analysis results indicate that a large audience regularly visits A‐list blogs, and their quotations and diffusion of information promote A‐list bloggers' reputations and build social capital, which consequently provides opportunities to convert popularity into a profit source. Finally the text analysis results show that A‐list bloggers often share positive life experiences in their blogs and receive positive feedback from their audience, which may increase their psychological well‐being and life satisfaction, and motivate them to continue writing. The positive emotions of A‐list bloggers may affect their audience and create emotional resonance with them.

Originality/value

This is the first study to explore the success of continuously popular A‐list bloggers to increase the understanding of the blogging phenomenon.

Abstract

Purpose

The assembly quality of complex products is pivotal to their lifecycle performance. Assembly precision analysis (APA) is an effective method used to check the feasibility and quality of assembly. However, there is still a need for a systematic approach to be developed for APA of kinematic mechanisms. To achieve more accurate analysis of kinematic assembly, this paper aims to propose a precision analysis method based on equivalence of the deviation source.

Design/methodology/approach

A unified deviation vector representation model is adopted by considering dimension deviation, geometric deviation, joint clearance and assembly deformation. Then, vector loops and vector equations are constructed, according to joint type and deviation propagation path. A combined method, using deviation accumulation and sensitivity modeling, is applied to solve the kinematic APA of complex products.

Findings

When using the presented method, geometric form deviation, joint clearance and assembly deformation are considered selectively during tolerance modeling. In particular, the proposed virtual link model and its orientation angle are developed to determine joint deviation. Finally, vector loops and vector equations are modeled to express deviation accumulation.

Originality/value

The proposed method provides a new means for the APA of complex products, considering joint clearance and assembly deformation while improving the accuracy of APA, as much as possible.

Abstract

Purpose

This paper aims to measure new product success within a Dutch mailing company and to hypothesize that there exists no definition of new product success which is generally applicable, or valid in all circumstances. It seeks to opine that the best that can be achieved is a “local” definition: a definition valid only in a specific local context. In this article, a method is described on how to develop such a local measure.

Design/methodology/approach

To prevent this framing bias, a multidimensional scaling approach is used, in which data collection and analysis have relevant new product success features as output instead of input.

Findings

The method was applied to a Dutch mailing company, and it was found that in this case only two dimensions of new product success were prevalent. These were ROI and customer acceptance. From this, it was inferred that local valid measures in this particular situation were only a subset of all measures of new product success mentioned in the literature. Originality/value – In summary, the method used could shed light on the difficulties that sometimes do arise when different parties are working together. As a consequence, not only researchers but also practitioners should become aware of the indefiniteness of the concept of new product success.
