Abstract

Purpose

This paper aims to propose a robust method for non-rigid point set registration, using the Gaussian mixture model and accommodating non-rigid transformations. The posterior probabilities of the mixture model are determined through the proposed integrated feature divergence.

Design/methodology/approach

The method involves an alternating two-step framework, comprising correspondence estimation and subsequent transformation updating. For correspondence estimation, integrated feature divergences including both global and local features, are coupled with deterministic annealing to address the non-convexity problem of registration. For transformation updating, the expectation-maximization iteration scheme is introduced to iteratively refine correspondence and transformation estimation until convergence.

Findings

The experiments confirm that the proposed registration approach exhibits remarkable robustness on deformation, noise, outliers and occlusion for both 2D and 3D point clouds. Furthermore, the proposed method outperforms existing analogous algorithms in terms of time complexity. Application of stabilizing and securing intermodal containers loaded on ships is performed. The results demonstrate that the proposed registration framework exhibits excellent adaptability for real-scan point clouds, and achieves comparatively superior alignments in a shorter time.

Originality/value

The integrated feature divergence, involving both global and local information of points, is proven to be an effective indicator for measuring the reliability of point correspondences. This inclusion prevents premature convergence, resulting in more robust registration results for our proposed method. Simultaneously, the total operating time is reduced due to a lower number of iterations.

Abstract

Purpose

Paramedics became nationally registered in 2018 in Australia. Prior to this, there was no central regulation of the profession with reliance on organisational regulation through employers. As paramedics expanded their scope, role and range of employers, especially outside statutory agencies, there was increasing need to engage in professional regulation. Regulation is more than a legal and bureaucratic framework. The purpose of the paper states that the way paramedics interact with their new regulatory environment impacts and is influenced by the professionalisation of the discipline. Regulation also redefines their positionality within the profession.

Design/methodology/approach

Two mixed-method surveys were undertaken. A pre-registration survey occurred in the month prior to regulation commencing (N = 419) followed by the second survey 31 months later (N = 407). This paper reports the analysis of qualitative data from the post-registration survey and provides comparison to the pre-registration survey which has been previously reported. Analysis was undertaken using interpretive phenomenological analysis (IPA).

Findings

Themes from the pre-registration survey continued however became more nuanced. Participants broadly supported registration and saw it as empowering to the profession. Some supported registration but were disappointed by its outcome, others rejected registration and saw it as divisive and oppressive.

Originality/value

Paramedics are beginning to come to terms with increasing professionalisation, of which regulation is one component. Changes can be seen in professional identity and engagement with professional practice; however, this is nascent and is deserving of additional research to track the profession as it continues to evolve.

Abstract

Purpose

Since 2018, Australian paramedics have been regulated under the National Registration and Accreditation Scheme (NRAS) for health practitioners. Established professions have been regulated in Australia for some time, so there is limited knowledge of their entry to regulation. However, as paramedicine has not been previously centrally regulated, this provides a unique case study to explore the transition to regulated practice.

Design/methodology/approach

Australian paramedics undertook two surveys: pre- and post-introduction of registration. The first survey was in the month leading up to the commencement of registration (N = 419), and the second survey took place 31 months after registration (N = 407). This paper presents the results of statistical analyses of the post-registration survey including comparisons to the pre-registration survey.

Findings

Although support for regulation has increased over time, there remains strong dissent consistent with 2018 levels. After 31 months of regulation, respondents reported increasing knowledge of the scheme and greater ease of navigation. The impacts of regulation are more nuanced and less polarised than in the first survey. Identity is again canvassed, and results suggest a shift from employment status and qualifications as key elements of identity to a community of practice and registration.

Originality/value

Paramedics' experiences and understanding of the rationale for registration are developing. Further support is needed to assist with the emerging professional identity and behaviours. Regulation is one of many occupational factors influencing professional identity and professionalism. Exploring the experience of regulation potentially assists regulators in better supporting practitioners and helps better understand professional evolution.

Abstract

Purpose

The purpose of this paper is to explore the factors that influence migrant workers' household registration transfer willingness at both individual and urban levels and to provide empirical evidence on adjusting the household registration system to accommodate economic development and migrant workers' imbalances.

Design/methodology/approach

This paper adopts a hierarchical nonlinear model and examines individual and urban influencing factors of migrant workers' household registration transfer willingness, based on the data from China Migrants Dynamic Survey (CMDS) and the Urban Statistical Yearbooks.

Findings

This paper shows that: (1) multi-factors, such as age, education, marital status, household demographics, industry and migrant workers' contract coverage, have significant effects on migrant workers' household registration transfer willingness; (2) The urban public service equalization indicators, such as regional economic, educational resources, medical care and ecological quality, have significant effects on migrant workers' willingness to transfer household registration; (3) The heterogeneity of migrant workers' willingness to transfer household registration is significant in central, eastern and western China.

Research limitations/implications

The authors provide a fresh perspective on population migration research in China and other countries worldwide based on the pull–push migration theory, which incorporates both individual and macro (urban) factors, enabling a comprehensive examination of the factors influencing household registration transfer willingness. This hierarchical ideology and approach (hierarchical nonlinear model) could be extended to investigate the influencing factors of various other human intentions and behaviors.

Originality/value

Micro approaches (individual perspective) have dominated existing studies examining the factors influencing migrant workers' household registration transfer willingness. The authors combine individual and urban perspectives and adopt a more comprehensive hierarchical nonlinear model to extend the empirical evidence and provide theoretical explanations for the above issues.

Abstract

Purpose

There is a long-standing debate about the relationship between land title registration and tenure security. Studies in the developing world point to a tenuous link between land registration and stable land tenure. The reason why people continue to register therefore becomes a mystery if tenure security is not entirely assured. This article focuses on the increase in property value as one such factor that induces title registration. Previous studies have quantified the economic impact of title registration on property values. However, the impact varies from city or country to another. The authors seek to investigate the extent of property value increment in Accra attributable to land title registration.

Design/methodology/approach

The authors statistically analyzed a data set from two institutions (First National Bank and the Lands Commission) in Ghana using a quantitative technique.

Findings

The authors discovered that, holding all other factors constant, the value of the land in Accra increases by 22.6% due to land title registration. This shows that lessees must register to enhance property values, even though the essential due diligence must be done to make sure the acquisition is free from liens and legal disputes.

Practical implications

This article highlights the implication of the findings for land administration as well as the practice of property valuation, development and brokerage in Ghana and Global South more broadly.

Originality/value

This is one of the first studies in Ghana to investigate the specific premium that housing markets put on land title registration.

Abstract

We study ceremonial adoption of voluntary standards, where participants adopt the standard in principle but do not change their practices. Ceremonial adoption can benefit individual participants, who may be able to reap the benefits of association with the standard at lower cost, but it can be problematic for overall levels of adoption. We conceive of ceremonial adoption as an interaction between strategic incentives of participants and social ties to their audiences, such that not all participants are likely to ceremonially adopt. Our setting is the Leadership in Energy and Environmental Design (LEED) certification for sustainable construction. We study the conditions under which projects register for LEED certification, allowing them to claim affiliation with LEED, but then do not actually finish certification. While our data are correlational in nature, our results suggest that studying the competition for audience members (in our case, occupants) can provide greater understanding of certification behavior as well as overall levels of adoption. Our findings have implications for organizations that design and maintain voluntary standards and for organization theorists who wish to understand field-level change. Thus, we provide more evidence that strategy and organizational theory interact in important and often unexamined ways.

Abstract

Purpose

Hull block assembly is a vital task in ship construction. It is necessary to obtain the actual poses of the assembly features to guide further block alignment. Traditional methods use single-point measurement, which is time-consuming and may lead to loss of key information. Thus, large-scale scanning is introduced for data acquisition, and this paper aims to provide a precise and robust method for retrieving poses based on point set registration.

Design/methodology/approach

The main problem of point registration is to find the correct transformation between the model and the scene. In this paper, a vote framework based on a new point pair feature is used to calculate the transformation. First, a special edge indicator for multiplate objects is proposed to determine the edges. Subsequently, pair features with an edge description are noted for every point. Finally, a voting scheme based on agglomerative clustering is implemented to determine the optimal transformation.

Findings

The proposed method not only improves registration efficiency but also maintains high accuracy compared to several commonly used approaches. In particular, for objects composed of plates, the results of pose estimation are more promising because of the compact pair feature. The multiple ship longitudinal localization experiment validates the effectiveness in real scan applications.

Originality/value

The proposed edge description performs a better detection for the edges of multiplate objects. The pair feature incorporating the edge indicator is more discriminative than the original template, resulting in better robustness to outliers, noise and occlusions.

Abstract

Purpose

This paper aims to describe how one medical library implemented a new scheduling system, initiated data analysis and modified its regularly scheduled workshop program because of evidence-based decision-making. Academic libraries that struggle with workshop attendance may use this process as a model.

Design/methodology/approach

Workshop registration data analysis focused on registrants' affiliation, role and location, and how registrants learned of workshops. Workshop attendance data analysis focused on which workshops, days, times of the day and months had the highest attendance. The analysis led to changes in marketing and targeted scheduling of future workshops by the time of day, day of the week and month of the year.

Findings

Data collected for four years, fall 2018 – summer 2022 (12 semesters), shows a steady increase in the number of people attending library workshops. The increase in attendance and ROI experienced after the changes implemented at Ruth Lilly Medical Library (RLML) is significant as libraries often struggle with attendance, marketing and return on investment when offering ongoing educational workshops.

Originality/value

Many libraries offer ongoing workshops with low attendance. This article provides an example of how one library changed software and registration and implemented evidence-based decision-making related to scheduling which may have contributed to an increase in workshop attendance. Other academic libraries might consider adopting similar software and evidence-based decision-making to improve their library workshop service.

Abstract

Purpose

Starting from intention–behaviour models and building upon the growing evidence that aggregated internet search query data represent a good proxy of human interests and intentions. The purpose of this study is to demonstrate that the internet search traffic information related to the selected key terms associated with establishing new businesses, reflects well the dynamics of entrepreneurial activity in a country and can be used for predicting entrepreneurial activity at the national level.

Design/methodology/approach

Theoretical framework is based on intention–behaviour models and supported by the knowledge spillover theory of entrepreneurship. Monthly data on new business registration from 2018 to 2021 is derived from the open database of the Russian Federal Tax Service. Terms of internet search interest are identified through interviews with the recent founders of new businesses, whereas the internet search query statistics on the identified terms are obtained from Google Trends and Yandex Wordstat.

Findings

The results suggest that aggregated data about web searches related to opening a new business in a country is positively correlated with the dynamics of entrepreneurial activity in the country and, as such, may be useful for predicting the level of that activity.

Practical implications

The results may serve as a starting point for a new approach to measure, monitor and predict entrepreneurial activities in a country and can help in better addressing policymaking issues related to entrepreneurship.

Originality/value

To the best of the authors’ knowledge, this study is original in its approach and results. Building on intention–behaviour models, this study outlines, to the best of the authors’ knowledge, the first usage of big data for analysing the intention–behaviour relationship in entrepreneurship. This study also contributes to the ongoing debate about the value of big data for entrepreneurship research by proposing and demonstrating the credibility of internet search query data as a novel source of quality data in analysing and predicting a country’s entrepreneurial activity.

The purpose of this study is to implement lean six sigma (LSS) methodology to improve the admission process in a higher education institute (HEI).

Abstract

Purpose

The purpose of this study is to implement lean six sigma (LSS) methodology to improve the admission process in a higher education institute (HEI).

Design/methodology/approach

In this study, case study research methodology is adopted and implemented through an LSS define-measure-analyze-improve-control (DMAIC) framework.

Findings

The preliminary investigation showed that the completion of the whole admission process of a new student takes an average of 88 min, which is equivalent to a sigma level of about 0.71 based on the targeted admission cycle time of 60 min. The implementation of the proposed LSS approach increased the sigma level from 0.71 to 2.57, which indicates a reduction in the mean admission cycle time by around 55%. This substantial improvement is expected not only to provide an efficient admission process but also to enhance the satisfaction of students and employees and increase the reputation of the HEI to a significant level.

Research limitations/implications

In this study, the sample size used in the analysis is considered small. In addition, the effectiveness of the proposed approach is investigated using a discrete event simulation with a single-case study, which may limit generalization of the results. However, this study can provide useful guidance for further research for the generalization of the results to wider scopes in terms of different sectors of HEIs and geographical locations.

Practical implications

This study uses several statistical process control tools and techniques through a LSS DMAIC framework to identify and element the root causes of the long admission cycle time at a HEI. The approach followed, and the lessons learned, as documented in the study, can be of a great benefit in improving different sectors of HEIs.

Originality/value

This study is one of the few attempts to implement LSS in HEIs to improve the administrative process so that better-quality services can be provided to customers, such as students and guardians. The project is implemented by a group of undergraduate students as a part of their senior design project, which paves the way for involving students in future LSS projects in HEIs. This study is expected to help to improve understanding of how LSS methodology can be implemented in solving quality-related problems in HEIs and to offer valuable insights for both academics and practitioners.
