This paper aims to present a method for improving the performance of the visual-inertial navigation system (VINS) by using a bio-inspired polarized light compass.

The measurement model of each sensor module is derived, and a robust stochastic cloning extended Kalman filter (RSC-EKF) is implemented for data fusion. This fusion framework can not only handle multiple relative and absolute measurements, but can also deal with outliers, sensor outages of each measurement module.

The paper tests the approach on data sets acquired by a land vehicle moving in different environments and compares its performance against other methods. The results demonstrate the effectiveness of the proposed method for reducing the error growth of the VINS in the long run.

The main contribution of this paper lies in the design/implementation of the RSC-EKF for incorporating the homemade polarized light compass into visual-inertial navigation pipeline. The real-world tests in different environments demonstrate the effectiveness and feasibility of the proposed approach.

Beginning farmers and ranchers (BFRs) are more likely to access land through an unrelated landowner than through family. Thus, farm and ranch owners who might transfer their land or businesses out of family are potential sources of land access for BFRs and are the most frequent participants in incentive programs to facilitate land transfer to BFRs. To assist in identifying landowners who might transfer out of family, the paper aims to explore similarities and differences between landowners according to their expectations for intra-familial versus extra-familial farm transfer.

Pairwise and regression analysis of USA Midwestern and Plains landowners' responses to an online survey (n = 322).

Landowners who might transfer out of family were likely to need the proceeds from a land sale to finance their retirement. Landowners' financial needs interacted with their widespread interest in transferring to a BFR such that 97% of owners who expected extra-familial transfer wanted to transfer to a BFR. There were also statistical patterns around the size of owners' landholdings in relation to their transfer plans.

This exploratory inquiry suggests patterns for future research to examine, especially around landowners' juxtaposition of their retirement income and their interest in transferring to a BFR and how to align these priorities and values.

By exploring the characteristics of landowners who are the most likely to provide land access to BFRs, the authors begin to examine how to target these owners in program outreach. Patterns for further exploration point to landowners' financial needs in relation to their interest in helping a BFR to get started in agriculture.

This study aims to explore the interplay between regulatory, normative and cultural-cognitive factors in the context of sustainability-driven organisational change in Mexican small and medium-sized enterprises (SMEs).

By contrasting a contingency with a universal approach to business excellence models (BEMs), the purpose of this paper is to investigate the effect of size on the use of the European Foundation for Quality Management (EFQM) model by organizations that were officially “Recognized for Excellence” in Spain. It considers the potential differences between large organizations and SMEs on the level of adoption of EFQM criteria and on the impact that enablers-criteria may have on key performance measures.

This study uses actual sub-criteria and criteria scores attained by organizations in their assessment for EFQM recognition. Scores of a population of 216 organizations are analyzed via analysis of variance, factor and structural equations models.

Although there are some criteria in the EFQM model that appear to be universally adopted irrespective of size, the empirical analyses indicate that size may shape the adoption of other criteria and the impact that enablers can have on results, thus supporting a contingency perspective. Moreover, the findings call for the revision of the relationships embedded in the EFQM model.

In contrast to most previous research, which relied on surveys of managers’ perceptions, this study uses the actual scores achieved by organizations in their assessment for EFQM recognition. It addresses the effect of size on the whole model, which so far has been neglected in the literature. All in all this study contributes to the literature on contingency approaches to best practices, and more specifically to BEMs. To the practitioner, it provides guidelines for addressing perceived performance gaps in their pursuit of recognition for excellence.

The purpose of this study is to assess the extent to which the Ghana stock market performance has been impacted by the novel COVID-19 pandemic.

The study used the exponential generalized autoregressive conditional heteroscedasticity (EGARCH) model, by using daily time series data from 2 January 2015 to 13 October 2020. Both pre-estimation (Augmented Dickey-Fuller and Phillips-Perron) and post-estimation tests (Jarque-Bera) were conducted to validate the results.

While the study shows a statistically insignificant negative relationship between the COVID-19 pandemic and the Ghana stock returns, the results confirm that the COVID-19 pandemic has occasioned an increase in the Ghana stock returns volatility by 8.23%. Furthermore, the study confirmed the presence of volatility clustering and asymmetric effect, with the latter implying that worthy news tends to affect volatility more than unwelcome news of equal size.

To dampen uncertainties that trigger stock market volatility, the government should surgically target worse affected COVID-19 pandemic businesses and households to check the drop in profits and demand. Rigidities associated with stock market operations must be addressed to make it attractive to investors even in the midst of a pandemic.

This paper is a pioneer attempt at assessing the extent to which a developing economy stock market has been impacted by the novel COVID-19 pandemic using the EGARCH model.

The aim of this study is to increase the understanding of collaborative relationships and assess according to the project size, the influence of the contributory factors in shaping collaboration network structure in projects developed in global supply chains (GSC).

The paper used a case study methodology applied to eight global projects developed by an Austrian company leader in global market intra-logistics solutions and warehouse automation. The cases were studied by two approaches in network analysis. First, visual and descriptive analysis to describe structural aspects of the network. Second, stochastic network analysis to evaluate the influence of contributory factors in the structure of the collaboration network.

The results evidence that independently of the project size and project manager influence, project team roles (PTR) who have a reciprocal communication among other PTR tend to have a higher collaboration intensity (CI). Additionally, the results highlight the influence of the project manager in shaping the collaboration network in standard projects (STP) and small projects (SMP). According to the project size, the results show that the PTR that form complete triangles or cluster or who communicate frequently among each other tend to have a high CI, being more evident these tendencies in large-scale projects than STP and SMP.

This research provides a framework to identify the key actors and contributory factors in shaping collaborative relationships in GSC. The findings could be used to support the decision-making process and formulation strategies for effective collaborative relationship management in GSC.

This article serves as an introduction to six articles featured in a special issue on diversity in the work–life interface. This collection of papers contains research that contemplates the work–life interface in different geographic and cultural contexts, that explores the work–life experiences of minority, marginalized and/or underresearched groups of workers and that takes into account diverse arrangements made to fulfill both work and nonwork responsibilities.

This introductory article first summarizes some of the emerging research in this area, introduces the papers in this special issue and links them to these themes and ends with highlighting the importance of using an intersectional lens in future investigations of the work–life interface.

These six articles provide empirically based insights, as well as new theoretical considerations for studying the interface between paid work and personal life roles. Compelling new research directions are identified.

Introducing the new articles in this special issue and reviewing recent research in this area brings together the work–life interface scholarship and diversity management studies and points to the necessity for future investigations to take an intersectional and contextualized approach to their subject matter.

The purpose of this paper is to examine how policy instability is priced in interest rates. Policy instability refers to the likelihood that the current policy will be changed in the future in the absence of political power shifts.

Chinese government’s experimental policy-making approach provides an ideal set of frequent policy flip-flops which allows us to identify the effect of policy changes.

Conditional on the bureaucratic quality of policymaking, a good-quality policy reversal is related to reductions in interest rate term spread and volatility; a bad-quality policy reversal is related to increases in the spread and volatility. The bureaucratic quality is multi-dimensional and the moderating effect is stronger on interest rates when it is measured more precisely.

First, we can use the interest rate dynamics to infer the policy risk premium, which is a more objective market indicator of the bureaucratic quality of the policy change. Second, the study is among the first that documents the pricing of policy instability can be moderated by the bureaucratic quality. The results indicate that it is important for a government to be responsive and consistent in liberalizing the financial market. It will lead to reduced cost of capital and volatility for investors and firms in the economy. Third, given that the bureaucratic quality is multi-dimensional and produces stronger impact jointly, a country shall continue to improve on different aspects of the bureaucratic quality. Although the study is based on the empirical evidence from Chinese policy environment, the results can be broadly applied to any developing economies that intend to liberalize the market to spur economic growth.

Virtual teams allow companies to recruit the best talents, regardless of their geographic location, which is particularly relevant in the Information and Communications Technology (ICT) sector given the high shortage of qualified human capital. However, the space and time flexibility of these professionals also present other challenges to Human Resource Management, such as work engagement and employee retention. This study aims to assess the extent to which supervisor support can influence work engagement and turnover intention in virtual teams.

We use a sample of 420 ICT Portuguese professionals who work in virtual teams to test a conceptual model with partial least squares (PLS).

The study results show that supervisor support decreases employee's intention to leave their job. We also found that work engagement mediates the relationship between supervisor support and work engagement. Results show that older employees present higher levels of work engagement and employees with longer tenure perceive less supervisor support.

This study contributes to elucidate the role played by supervisors in influencing employee engagement and retention in virtual work environments.
