Abstract

Purpose

Experiments are the backbone of the development process of data-driven predictive models for scientific applications. The quality of the experiments directly impacts the model performance. Uncertainty inherently affects experiment measurements and is often missing in the available data sets due to its estimation cost. For similar reasons, experiments are very few compared to other data sources. Discarding experiments based on the missing uncertainty values would preclude the development of predictive models. Data profiling techniques are fundamental to assess data quality, but some data quality dimensions are challenging to evaluate without knowing the uncertainty. In this context, this paper aims to predict the missing uncertainty of the experiments.

Design/methodology/approach

This work presents a methodology to forecast the experiments’ missing uncertainty, given a data set and its ontological description. The approach is based on knowledge graph embeddings and leverages the task of link prediction over a knowledge graph representation of the experiments database. The validity of the methodology is first tested in multiple conditions using synthetic data and then applied to a large data set of experiments in the chemical kinetic domain as a case study.

Findings

The analysis results of different test case scenarios suggest that knowledge graph embedding can be used to predict the missing uncertainty of the experiments when there is a hidden relationship between the experiment metadata and the uncertainty values. The link prediction task is also resilient to random noise in the relationship. The knowledge graph embedding outperforms the baseline results if the uncertainty depends upon multiple metadata.

Originality/value

The employment of knowledge graph embedding to predict the missing experimental uncertainty is a novel alternative to the current and more costly techniques in the literature. Such contribution permits a better data quality profiling of scientific repositories and improves the development process of data-driven models based on scientific experiments.

Abstract

Purpose

The purpose of this study is to extend the research on fashion renting (FR) by investigating how personal and social motives (i.e. “subjective norms”, “perceived behavioural control”, “sustainable orientation” and “FR benefits”) affect consumers’ attitudes and intentions towards it. In addition, personality traits are investigated as potential antecedents of FR, resulting in the proposal of an overall framework that combines the theory of planned behaviour with the trait theory approach.

Design/methodology/approach

Data were collected in Italy from a sample of 694 consumers, mainly females (88%), with an average age of 28.8 years and coming from all over the country. The collected data were then processed via structural equation modelling.

Findings

The results indicated that intention towards FR is influenced by attitude, which, in turn, is affected by social norms, perceived behavioural control, sustainable orientation and FR benefits. Furthermore, only fashion leadership acts as a direct antecedent of FR attitude, while the need for uniqueness and materialism plays critical roles as predictors of personal and social motives. Subjective norms and perceived behavioural control also serve as mediators of the significant relationships between personality traits and attitudes towards FR.

Practical implications

The study provides useful implications for fashion rental companies in attracting consumers and offers a foundation for further research on transforming traditional consumption into a more sustainable one.

Originality/value

The study presents new knowledge on the rental phenomenon in the fashion sector by responding to the call to deepen the analysis of factors that influence consumers’ adoption of FR from the perspectives of personal and social motives and personality traits.

Abstract

Purpose

This study explores the relationship between economic freedom and gender ideologies on the allocation of women’s opportunity-to-necessity entrepreneurship across countries. Opportunity entrepreneurship is typically understood as one’s best option for work, whereas necessity entrepreneurship describes the choice as driven by no better option for work. Specifically, we examine how economic freedom (i.e. each country’s policies that facilitate voluntary exchange) and gender ideologies (i.e. each country’s propensity for gendered separate spheres) affect the distribution of women’s opportunity-to-necessity entrepreneurship across countries.

Design/methodology/approach

We construct our sample by matching data from the following country-level sources: the Global Entrepreneurship Monitor’s Adult Population Survey (APS), the Fraser Institute’s Economic Freedom Index (EFI), the European/World Value Survey’s Integrated Values Survey (IVS) gender equality index, and other covariates from the IVS, Varieties of Democracy (V-dem) World Bank (WB) databases. Our final sample consists of 729 observations from 109 countries between 2006 and 2018. Entrepreneurial activity motivations are measured by the ratio of the percentage of women’s opportunity-driven total nascent and early-stage entrepreneurship to the percentage of female necessity-driven total nascent and early-stage entrepreneurship at the country level. Due to a first-order autoregressive process and heteroskedastic cross-sectional dependence in our panel, we estimate a fixed-effect regression with robust standard errors clustered by country.

Findings

After controlling for multiple macro-level factors, we find two interesting findings. First, economic freedom positively affects the ratio of women’s opportunity-to-necessity entrepreneurship. We find that the size of government, sound money, and business and credit regulations play the most important role in shaping the distribution of contextual motivations over time and between countries. However, this effect appears to benefit efficiency and innovation economies more than factor economies in our sub-sample analysis. Second, gender ideologies of political equality positively affect the ratio of women’s opportunity-to-necessity entrepreneurship, and this effect is most pronounced for efficiency economies.

Originality/value

This study offers one critical contribution to the entrepreneurship literature by demonstrating how economic freedom and gender ideologies shape the distribution of contextual motivation for women’s entrepreneurship cross-culturally. We answer calls to better understand the variation within women’s entrepreneurship instead of comparing women’s and men’s entrepreneurial activity. As a result, our study sheds light on how structural aspects of societies shape the allocation of women’s entrepreneurial motivations through their institutional arrangements.

Abstract

Purpose

The relationship between trust, accountability and procedural justice is studied via research into British credit unions (CUs) following regulatory reform to remedy problems exposed by the 2007–2008 global financial crisis.

Design/methodology/approach

Interviews at 13 case studies of different types and sizes of credit unions in Glasgow, Scotland, are examined using template analysis and abductive theorizing to understand the effects of disproportionate reforms on small credit unions.

Findings

Smaller credit unions found three regulatory changes – namely dual regulators, increased minimum reserves and introduction of the Senior Managers and Certification Regime – excessive. Excessive change generated distrust in regulators. Regulators' insufficient attention to procedural justice contributed to this distrust.

Originality/value

Linkage of multidimensional confluent trust to a multilevel system of accountability provides an original way of understanding how indiscriminate attempts at trust repair damage some elements of trust in formal regulatory systems. Recognition of the need for procedural justice to enable smaller credit unions to articulate their extant checks and potential exemption from formal regulations provides another valuable contribution. The explanation of the abductive logic employed is also original.

Abstract

Purpose

The purpose of this study is to examine the politics, political economy, and fallout of hawkish regulatory policy on prescription drugs in Nigeria. Hawkish regulatory policy on prescription drug in Nigeria, such as opioid analgesics, is a very complex and multifaceted one, which usually involves the interplay of many factors and parties.

Design/methodology/approach

Policy manuals, official government gazettes (legislations, regulations, Acts and decrees), academic literature and a direct ethnographic observation of events surrounding the regulation of prescription drugs were reviewed and engaged.

Findings

The results revealed that Nigerian and global political economy and politics interface to define the direction of the new restrictive opioid policy, with resultant friction between prohibition and consumption. The reviews showed that the overarching “get-tough” and “repressive” policy are not necessarily founded on empirical evidence of an increase in prescription drug sales or use, but more as a product of the interplay of both internal and external politics and the prevailing socioeconomic order.

Practical implications

Instead of borrowing extensively from or being influenced by repressive Western drug laws and perspectives, Nigerian policymakers on prescription opioids should take control of the process by drawing up a home-grown policy that is less intrusive and punitive in nature for better outcomes. A mental sea change is required to understand the intrigues of Western power in Nigeria’s politics and political economy to avoid the continuous symptomatic failure of drug policy.

Originality/value

The politics and economic influence of the United Nations, USA and Western powers, as well as the axiom of moral panic of prescription drugs scares within the Nigerian environment, are particularly significant in the making of the emerging hawkish policy on prescription drugs in Nigeria.
