Abstract

Purpose

Previous RMIL versions of the conjugate gradient method proposed in literature exhibit sufficient descent with Wolfe line search conditions, yet their global convergence depends on certain restrictions. To alleviate these assumptions, a hybrid conjugate gradient method is proposed based on the conjugacy condition.

Design/methodology/approach

The conjugate gradient (CG) method strategically alternates between RMIL and KMD CG methods by using a convex combination of the two schemes, mitigating their respective weaknesses. The theoretical analysis of the hybrid method, conducted without line search consideration, demonstrates its sufficient descent property. This theoretical understanding of sufficient descent enables the removal of restrictions previously imposed on versions of the RMIL CG method for global convergence result.

Findings

Numerical experiments conducted using a hybrid strategy that combines the RMIL and KMD CG methods demonstrate superior performance compared to each method used individually and even outperform some recent versions of the RMIL method. Furthermore, when applied to solve an image reconstruction model, the method exhibits reliable results.

Originality/value

The strategy used to demonstrate the sufficient descent property and convergence result of RMIL CG without line search consideration through hybrid techniques has not been previously explored in literature. Additionally, the two CG schemes involved in the combination exhibit similar sufficient descent structures based on the assumption regarding the norm of the search direction.

Abstract

In recent years, many Western states have moved towards funding the asylum processing and resettlement systems of countries in the Global South. These forms of outsourced migration governance are upheld by a vast industry of state and non-state actors. This chapter draws on fieldwork conducted in the Republic of Nauru to look at the people and places on the frontlines of the extractive asylum industry. Using Alexander Weheliye’s (2014) concept of ‘racialising assemblages’, the author argues that outsourced asylum regimes exacerbate the continuous subjection of Indigenous and migrant communities to toxic practices and discourses. Outsourced asylum is a contemporary practice of resource extraction (much like other forms of mining) that builds on colonial extractive projects that disproportionately target communities of colour. Ongoing processes of dispossession and displacement are occurring as people and places are rendered into resources and frontline sites for the extractive asylum industry. This chapter also shows how humanitarian and liberal democratic discourses are part of the mechanics of racialised geopolitical ordering. Racialised refugees are made into destitute victims, whereas locals become brutish villains, rather than political subjects. In attending to the politics of refusal, where Nauruans and refugees refuse ingrained racialising assemblages that deny them personhood, the author stresses the importance of intersectional advocacy that highlights the toxic effects of extractive asylum regimes on local and migrant populations alike.

Abstract

Purpose

To increase the understanding of how entrepreneurship education impacts entrepreneurial careers, the purpose of the paper is to investigate the role that a venture creation program (VCP) might have in mitigating or surpassing a lack of other antecedents of entrepreneurial careers. In particular, the authors focus on entrepreneurial pedigree and prior entrepreneurial experience.

Design/methodology/approach

Data from graduates of VCPs at three universities in Northern Europe were collected through an online survey. Questions addressed graduate background prior to education, yearly occupational employment subsequent to graduation and graduates' own perceptions of entrepreneurial activity in employment positions. The survey was sent to 1,326 graduates and received 692 responses (52.2% response rate).

Findings

The type of VCP, either independent (Ind-VCP) or corporate venture creation (Corp-VCP), influenced the mitigation of prior entrepreneurial experience. Prior entrepreneurial experience, together with Ind-VCP, made a career as self-employed more likely. However, this was not the case for Corp-VCP in subsequently choosing intrapreneurial careers. Entrepreneurial pedigree had no significant effect on career choice other than for hybrid careers.

Research limitations/implications

Entrepreneurial experience gained from VCPs seems to influence graduates toward future entrepreneurial careers. Evidence supports the conclusion that many VCP graduates who lack prior entrepreneurial experience or entrepreneurial pedigree can develop sufficient entrepreneurial competencies through the program.

Originality/value

This study offers novel evidence that entrepreneurship education can compensate for a lack of prior entrepreneurial experience and exposure for students preparing for entrepreneurial careers.

Abstract

Purpose

This study aims to operationalize consumer decision-making styles as higher-order constructs and investigates the influence of two distinct subdimensions of consumer vanity – namely, appearance vanity and achievement vanity – on consumer decision-making orientations (CDMO).

Design/methodology/approach

Using data from an online survey of 319 young adults, the authors construct a higher-order structural model capturing the following three orientations: social/conspicuous, utilitarian and undesirable. The partial least squares structural equation modeling approach was used to test the validity of the higher-order structural model and the hypothesized relationships.

Findings

Results, confirming the higher-order structure of consumer decision-making styles, highlight the distinctive impacts of the vanity dimensions on different CDMOs. Specifically, appearance vanity predominantly affects social and undesirable orientations, and achievement vanity influences utilitarian orientation.

Originality/value

While several theoretical classifications of consumer decision-making styles have been proposed in the past, none of the earlier studies leveraged those classifications as higher-order models. Addressing this literature gap, this study provides empirical evidence associating CDMOs with a specific consumer trait – vanity – thereby validating the higher-order nature of consumer decision-making styles.

Abstract

Purpose

Children’s sensory involvement refers to the degree to which children engage their senses, such as sight, touch, taste, smell and hearing, in their interactions with the environment. In the context of parents' purchase decisions, children’s sensory involvement pertains to how children's sensory involvement influences the purchasing decisions made by their parents. The aim of this study was to evaluate the effect of children's sensory involvement on parents’ purchase decisions considering the mediating role of the parent’s attitude.

Design/methodology/approach

In this study, a structured questionnaire survey was conducted with parents of children aged 7–12 in Isfahan, Iran. The sample consisted of 210 parents, aimed at elucidating the relationship between variables. Structural equation modeling (SEM) was employed to analyze the relationship between variables.

Findings

Results showed a significant relationship between children’s sensory involvement and parents’ purchase decisions, children’s sensory involvement and parents’ attitudes and parents’ attitudes and purchase decisions. It was concluded that children’s sensory involvement could indirectly influence the parents’ purchase decisions considering the mediating role of parents' attitudes.

Originality/value

In today's business landscape, it is imperative for organizations to discern the multitude of factors influencing consumers' purchasing decisions. Among these, family dynamics play a substantial role, with children often exerting a strong influence on their parents' buying choices. Despite the acknowledged importance of this dynamic in existing literature, the specific impact of children's sensory involvement on parental purchasing decisions remains largely unexplored. Therefore, this paper aims to fill this gap in the literature by shedding light on the role of children's sensory involvement in shaping parental buying behaviors.

Abstract

Purpose

Employees facing challenges in their careers – i.e. female, migrant, elderly and lower-educated employees – might expect job searches to have a low likelihood of success and might therefore more often stay in unsatisfactory positions. The goal of this study is to discover inequalities in job mobility for these employees.

Design/methodology/approach

We rely on a large sample of Dutch public sector employees (N = 30,709) and study whether employees with challenges in their careers are hampered in translating job dissatisfaction into job searches. Additionally, we assess whether this is due to their perceptions of labor market alternatives.

Findings

Findings show that non-Western migrant, elderly and lower-educated employees are less likely to act on job dissatisfaction than their advantaged counterparts, whereas women are more likely than men to do so. Additionally, we find that although they perceive labor market opportunities as limited, this does not affect their propensity to search for different jobs.

Originality/value

This paper is novel in discovering inequalities in job mobility by analyzing whether employees facing challenges in their careers are less likely to act on job dissatisfaction and therefore more likely to remain in unsatisfactory positions.

Abstract

Purpose

Coronavirus disease 2019 (COVID-19) has made telecommuting widely valued, but different individuals have different degrees of acceptance of telecommuting. This article aims to identify suitable individuals for telework and to clarify which types of workers are suitable for what level of telework, set scientific, reasonable hybrid work ratios and processes and measure their suitability.

Design/methodology/approach

First, two working scenarios of different risk levels were established, and the theory of planned behavior (TPB) was used to introduce latent variables, constructing a multi-indicator multi-causal model (MIMIC) to identify suitable individuals, and second, constructing an integrated choice and latent variable (ICLV) model of the working method to determine the suitability of different types of people for telework by calculating their selection probabilities.

Findings

It is possible to clearly distinguish between two types of suitable individuals for telework or traditional work. Their behavior is significantly influenced by the work environment, which is influenced by variables such as age, income, attitude, perceived behavioral control, work–family balance and personnel exposure level. In low-risk scenarios, the influencing factors of the behavioral model for both types of people are relatively consistent, while in high-risk scenarios, significant differences arise. Furthermore, the suitability of telework for the telework-suitable group is less affected by the pandemic, while the suitability for the non-suitable group is greatly affected.

Originality/value

This study contributes to previous literature by: (1) determining the suitability of different population types for telework by calculating the probability of selection, (2) dividing telework and traditional populations into two categories, identifying the differences in factors that affect telework under different epidemic risks and (3) considering the impact of changes in the work scenario on the suitability of telework for employees and classifying the population based on the suitability of telework in order to avoid the potential negative impact of telework.

Abstract

Purpose

Recent developments in the EU’s anti-corruption strategy have brought the EU closer to meeting the UNCAC’s objectives, i.e. the Proposal for a Directive on combating corruption (2023) and the Proposal for a Directive on Asset Recovery and Confiscation (2022). This paper aims to discuss these developments from the perspective of the UNCAC, to identify missing elements in the EU’s asset recovery mechanisms.

Design/methodology/approach

Critical approach towards EU anti-corruption policy (discussing the problems and solutions). Review of EU developments in asset recovery law.

Findings

There is a political will on the part of the EU to fight corruption through the rules enshrined in the UNCAC. However, improving EU law by introducing a new type of confiscation of unexplained wealth and criminalising illicit enrichment, without establishing convergent rules for the return of corrupt assets from EU territory to the countries of origin, cannot be seen as sufficient action to achieve the UNCAC’s objectives. In modelling mechanisms of the return of assets, the EU should search for solutions to overcome the difficulties resulting from the ordre public clause remaining a significant factor conditioning mutual legal assistance.

Originality/value

This paper discusses the possible input of the EU, as a non-State Party to the UNCAC, to advance implementing the UNCAC solutions on asset recovery by establishing convergent rules for the return of corrupt assets from EU territory to countries of origin.

Abstract

Purpose

This research aims to offers a new method for assessing geoeconomic risks in bilateral relations and evaluate the level of such risks from Vietnam’s economic dependency on China.

Design/methodology/approach

I apply descriptive analysis to identify asymmetrical dependency in Vietnam–China economic relations and propose a geoeconomic risk assessment framework to evaluate risk levels in bilateral economic linkages.

Findings

The proposed geoeconomic risk framework assesses risk levels, which are positively influenced by the degree of asymmetrical relations (vulnerabilities), the net impacts on the receiving economy (impacts) and the sending state’s ability to control economic tools (threats). In contrast, risk levels are negatively affected by the effectiveness of existing mitigation efforts. The framework employs ordinal likelihood scales to rank various risk levels. In the context of Vietnam–China relations, market access for agricultural products and control of the Mekong water emerge as the most risky areas for economic coercion, followed by Chinese official development finance in infrastructure and critical input imports. On the other hand, debt dependency and foreign direct investment in the energy sector are considered more secure areas—less likely targets for economic coercion. Hence, risk mitigation strategies should prioritize reducing asymmetry in vulnerable dependence areas while maintaining current practices in more secure areas.

Originality/value

Methodologically, it introduces a new approach for assessing bilateral geoeconomic risk. Empirically, it provides Vietnam’s policymakers with a comprehensive evaluation of the implications of economic interdependence with China.

Abstract

Purpose

The purpose of this study is to develop a set of parameters universally acceptable for assessing design and construction strategies for reducing operational energy usage and its associated greenhouse gas (GHG) emission. Also, the parameters are intended to estimate the quantity of energy and its associated GHG emission reduction over the assessment period.

Design/methodology/approach

This study used five steps framework comprising definition of purpose, selecting the candidate parameters, criteria selection and description, selecting proposed parameters and defining the proposed parameters. The criteria used were the parameter’s prevalence, measurability, preference and feasibility toward adaptability to the relevant stakeholders.

Findings

This study consolidated 11 parameters. Seven cover designs and construction strategies comprising energy monitoring, natural lighting and ventilation design. Others are building thermal performance, efficient equipments, renewable energy and energy policy. The remaining four consider operational energy consumption, GHG emission quantification and their reduction over time.

Practical implications

Providing suitable indicators for assessing direct and indirect GHG emission with easily accessible data is essential for assessing built environment. The consolidated parameters can be used in developing rating systems, monitoring GHG inventories and activities of building related industries.

Originality/value

This study was conducted at the CEIES UTHM and used 11 existing rating systems open for research purposes, International Panel for Climate Change reports and GHG protocol report and guides and several other standards.
