Abstract
A thick film superconductor paste has been produced to determine the properties of granulated superconductor materials and to observe the percolation effect. The base of the paste was chosen to be of the BiSrCaCuO system because of its high Tc and advantageous current density properties. For contacts, a conventional Ag/Pt paste was used. The critical temperature was between 110 K and 115 K depending on the printed layer thickness. The critical current density was between 200 and 300 A/cm2. The R‐T and U‐l functions were measured with different parameters (Imeasuring. Bexternal. Number of layers, T). The measurement results confirmed the conducting mechanism theory in the material. A percolation structure model was built and is described. Finally, some fundamental advantages and problems of the process are discussed and the high‐frequency electric field sensor realised is described.

Abstract
Specially formulated frit materials have been applied in thick film superconductors similar to the standard thick film materials in order to achieve processing parameters closely compatible with conventional thick film technology and alumina substrates. The applied frits have improved the adhesion and superconductor properties at the same time due to a superconductor bridge formation between the grains. Both YBCO and BSCCO systems have been analyzed. The results are promising.

Abstract
Purpose
This paper investigates how outcomes-based performance management (PM) regimes operate in the partnerships known as social impact bonds (SIBs), which bring together partners from the public, private and third sectors. The findings are analysed in the light of the different cultural world views of the partners.
Design/methodology/approach
Published evaluations of 25 UK SIBs were analysed by a qualitative multiple case study approach. This study of secondary sources permitted the analysis of a wide range of SIB partnerships from near contemporary accounts.
Findings
Outcomes frameworks led to rigorous PM regimes that brought the cultural differences between partners into focus. While partnerships benefitted from the variety of viewpoints and expertise, the differences in outlook simultaneously led to strains and tensions. In order to mitigate such tensions, some stakeholders conformed to the outlooks of others.
Practical implications
The need to achieve a predefined set of payable outcomes embeds a “linear” view of intervention and effect on the SIB partners and a performance regime in which some partners dominate. In designing accountability systems for partnerships such as SIBs, commissioners should consider how the performance regime will affect the interests of all stakeholders.
Originality/value
This study adds to the cultural theory literature which has rarely considered three-way partnerships embodying hierarchical, individualist and egalitarian world views and how performance regimes operate in such partnerships. Three-way partnerships are thought to be rare and short-lived, but this empirical study shows that they can be successful albeit over a predefined lifespan.

Abstract
This article focuses on the consequences of having FraX‐E, the rare but well recognised variant of fragile X syndrome. The authors provide some background on the condition and report on recent research and evidence. Three case reports are outlined and the specific behavioural aspects of the syndrome are considered. The authors argue that it is important that the behavioural phenotype for FraX‐E is clearly identified and defined in order to give those with the condition relevant psychological and educational support in the future.

Abstract
Purpose
This paper aims to directly test the assertion by proponents of executive stock option repricing that repricing leads to increased management retention. Previous studies find either no effect or decreased retention following stock price repricing. This paper uses a more precise research design to re-examine the relationship between stock option retention and management retention.
Design/methodology/approach
The authors use an empirical methodology and construct a sample of 158 firms and 201 repricing events, and a control sample of 201 non-repricing firms. They then examine executive turnover in the four years following the stock option repricing event.
Findings
It was found that, consistent with agency theory, stock option repricing actually results in greater executive retention. Specifically, CEO retention is significantly greater for repricing firms relative to non-repricing firms for up to three years following the repricing date, and non-CEO executive retention is significantly greater for two years.
Research limitations/implications
Firms continue to restructure management through stock option repricing. However, recent option repricing has been undertaken during a period when the economy is in decline, making it is difficult to disentangle effects of option repricing on management retention. Hence, this paper uses repricing data from an earlier period, from 1992-1997, when the economy was good.
Originality/value
Many firms argue that when stock options are out-of-the-money and managerial talent is in demand, repricing executive stock options is necessary to retain managers. Previous studies find contradictory or no support for this view. Using a much more precise methodology, this paper shows that firms do retain managers when they reprice their options compared to when they do not.

Abstract
Purpose
This paper aims to examine the Islamic marketing literature to uncover potential customer adoption behaviours and enhance the effectiveness of blockchain-based halal logistics services in catering to customer demands. The findings of this paper provide substantial contributions to the realms of both halal logistics services and Islamic marketing literature, delineating future paths for research. By delving into halal logistics practices, integration procedures and service provider performance, this paper assists stakeholders in enhancing halal logistics services to meet the changing demands of customers effectively.
Design/methodology/approach
This paper uses a systematic review incorporating bibliometric analysis to examine past and contemporary research topics, selecting and appraising contributions while analysing and consolidating data. A methodical approach has been used to identify, assess and incorporate pertinent studies on Islamic characteristics, traceability technology, blockchain integration and halal logistics practices.
Findings
After screening and analysing 139 selected documents with the VOS viewer, it is evident that among a 1,000 keywords, 15 stand out in terms of frequency and link strength. The research highlights the considerable academic interest in themes such as “blockchain”, “halal logistics” and “supply chain”, underscoring their importance. The findings of this paper help bridge the gap in Islamic marketing by linking technology with religious values. It suggests that the integration of blockchain technology in halal logistics enhances operational efficiency while aligning with both operational and Islamic marketing principles, promoting ethical conduct and transparency as key enablers.
Practical implications
The theoretical significance of this paper lies in establishing a correlation among three key research domains: technology, symbolised by blockchain; customer-centric operations, incorporating the halal supply chain and logistics within Islamic marketing. The outcomes reflect consumer behaviour and Shariah compliance. This integration has the potential to introduce innovative theoretical frameworks that encompass religious ethics in marketing, logistics and technological advancements.
Originality/value
This paper comprehensively analyses the intersection between blockchain technology, halal logistics, supply chain management and Islamic marketing. The paper has comprehensively analysed previous studies and outlined the future research path for blockchain technology in halal logistics and its application in Islamic marketing literature.

Abstract
Purpose
Kids get exposed to advertising on social media platforms when they visit them to perform various goals. The purpose of this study is to find out the factors which affect kids' behaviour when the kids encounter advertising on social media and also to establish causal relationships amongst the factors of social media advertising (SMA).
Design/methodology/approach
A total of 11 factors of SMA have been identified with the help of experts and the causal relationships amongst the SMA factors have been constructed by the implementation of decision-making trail and laboratory evaluation (DEMATEL). Based on the established relationships, a causal diagram has been also developed to understand the structural nature of interdependence amongst the factors.
Findings
DEMATEL technique is based on logical steps, which have assisted in categorising the identified factors into two groups: cause group and effect group. Cause group factors are the reasons for the effect group factors to occur. Customisation, entertainment, information and interactivity have been observed as cause factors whereas, relevance, engagement with SMA, purchase intention, product involvement, advertising value, attitude towards SMA and irritation have been observed as effect factors. Product involvement is found to have the highest level of interaction with all other factors. Information and interactivity are observed to influence all other factors.
Research limitations/implications
Kids possess a limited understanding of the selling intent of advertisers which makes kids vulnerable to advertising. This study supports that the content of the advertisement should be kept in accordance with the need of kids and also suggests that marketers should emphasise cause group factors which derive subsequent consequences on effect group factors. The foremost limitation of this study lies in the process of identifying the factors through expert opinions. The sets of contextual relationships may vary when different experts are considered.
Originality/value
This study strives to identify the factors which affect kids' understanding of SMA and also establishes causal relationships amongst them. This kind of study is unique in state of the art and to the authors' knowledge no significant research has been conducted in India which involves establishment of inter-relationships amongst SMA factors that affect kids' behaviour.
