Abstract

Purpose

An individual’s driving style significantly affects overall traffic safety. However, driving style is difficult to identify due to temporal and spatial differences and scene heterogeneity of driving behavior data. As such, the study of real-time driving-style identification methods is of great significance for formulating personalized driving strategies, improving traffic safety and reducing fuel consumption. This study aims to establish a driving style recognition framework based on longitudinal driving operation conditions (DOCs) using a machine learning model and natural driving data collected by a vehicle equipped with an advanced driving assistance system (ADAS).

Design/methodology/approach

Specifically, a driving style recognition framework based on longitudinal DOCs was established. To train the model, a real-world driving experiment was conducted. First, the driving styles of 44 drivers were preliminarily identified through natural driving data and video data; drivers were categorized through a subjective evaluation as conservative, moderate or aggressive. Then, based on the ADAS driving data, a criterion for extracting longitudinal DOCs was developed. Third, taking the ADAS data from 47 Kms of the two test expressways as the research object, six DOCs were calibrated and the characteristic data sets of the different DOCs were extracted and constructed. Finally, four machine learning classification (MLC) models were used to classify and predict driving style based on the natural driving data.

Findings

The results showed that six longitudinal DOCs were calibrated according to the proposed calibration criterion. Cautious drivers undertook the largest proportion of the free cruise condition (FCC), while aggressive drivers primarily undertook the FCC, following steady condition and relative approximation condition. Compared with cautious and moderate drivers, aggressive drivers adopted a smaller time headway (THW) and distance headway (DHW). THW, time-to-collision (TTC) and DHW showed highly significant differences in driving style identification, while longitudinal acceleration (LA) showed no significant difference in driving style identification. Speed and TTC showed no significant difference between moderate and aggressive drivers. In consideration of the cross-validation results and model prediction results, the overall hierarchical prediction performance ranking of the four studied machine learning models under the current sample data set was extreme gradient boosting > multi-layer perceptron > logistic regression > support vector machine.

Originality/value

The contribution of this research is to propose a criterion and solution for using longitudinal driving behavior data to label longitudinal DOCs and rapidly identify driving styles based on those DOCs and MLC models. This study provides a reference for real-time online driving style identification in vehicles equipped with onboard data acquisition equipment, such as ADAS.

Abstract

Purpose

As a Quality Management (QM) framework, the European Foundation for Quality Management (EFQM) Excellence Model has stakeholder management at its core. In EFQM (2012), based on which assessments were made until 2021, “creating a sustainable future” was a fundamental principle, but how it translated to a Sustainability Orientation and delivered to stakeholders remains questionable. This study aims to investigates the Sustainability Orientation within EFQM (2012) and its associations with Results for stakeholders.

Design/methodology/approach

Longitudinal assessments of recognized-for-excellence organizations by a partner of EFQM are considered. Using factor analysis, scores on the sub-criteria that defined “creating a sustainable future” are investigated, and a Sustainability Orientation is inferred. Panel regressions and structural equation modeling assess the correlations between Sustainability Orientation and Results. A qualitative analysis follows, where sustainability reports from role-models within this population are text mined to examine whether and how they reflected the guidance in EFQM (2012) concerning “creating a sustainable future”.

Findings

Direct and indirect positive associations between the Sustainability Orientation implied by EFQM (2012) and stakeholder-performance are confirmed. Yet, inferences from text mining of reported priorities of role-models of excellence illustrate that EFQM (2012) might have driven different strategies towards sustainability.

Originality/value

Despite conceptualizations that the EFQM model embeds a Sustainability Orientation, to the best of the researchers’ knowledge, its existence and likely impact remain to be examined. By combining longitudinal statistical analysis, structural equation models and text mining, consistent insights on the link between Sustainability Orientation and organizational performance are obtained.

Abstract

Purpose

The purpose of this article is to describe and analyze the occupational life cycle of Swedish real estate brokers.

Design/methodology/approach

Voluntary turnover among real estate brokers could lead to occupational turnover and/or employee turnover and has been described as problematic by both practitioners and researchers alike. Most previous studies focusing on this issue have explored connections between real estate brokers' personality, economic and market conditions and turnover. Employee turnover involves shifting jobs within the profession (real estate brokerage), whereas occupational turnover concerns movement to a job not related to the real estate brokerage profession. Both perspectives on turnover are however lacking data about the average time spent as a broker. This study fills this gap by exploring real estate brokers' life cycle through data analysis using a cohort study consisting of a sample of 5,304 real estate brokers registered and/or deregistered over a ten-year period from 2010 to 2019.

Findings

The analysis show that the decline is almost linear, resulting in 50% of the newly registered real estate brokers remain in the occupation eight years after registration. These findings are not in line with previous assumptions as the real estate brokers' life cycle is substantially longer. The results also reveal that there are differences in life cycles due to gender and year of registration.

Originality/value

The analysis of longitudinal, aggregated data on the life cycle of real estate brokers is highly relevant as it serves as a point of reference for future longitudinal studies analyzing the motives for leaving the occupation.

Abstract

Purpose

Retirement is a complex process that can impact daily lives and relationships. While some gender differences in academic retirement experiences have been noted, few studies have focused exclusively on women academics’ retirement experiences. This follow-up study aims to explore the meaning of retirement and its impact on retired women academics' daily lives and relationships over time from an occupational perspective.

Design/methodology/approach

Using a qualitative, longitudinal descriptive design, semi-structured interviews (n = 11) were completed with women retirees from one university and an academically linked university-level, college of education and liberal arts, in the Republic of Ireland (n = 11). This paper presents the findings of follow-up interviews conducted one year later (n = 10). Data were analysed using Braun and Clarke’s six-phase thematic analysis. A longitudinal analysis was then undertaken using a recurrent cross-sectional approach (Grossoehme and Lipstein, 2016) to enable discussion of changes and continuity that had occurred over time in their daily lives.

Findings

The analysis yielded four themes: (i) continuing to navigate occupational identity challenges, (ii) structuring free time, (iii) appreciating health and well-being and (iv) continuing meaningful professional relationships and activities. Participants described on-going occupational identity challenges linked with contextual factors and experiences of occupational injustices of lack of recognition, lack of inclusion and a lack of choice to continue working in their paid academic employment.

Originality/value

These findings suggest that occupational therapists advocate for older adults, so that meaningful choices in retirement timing can be offered to all equally and so that older people are acknowledged for their contributions to society.

Abstract

Purpose

This study attempts to answer how values and holiday preferences were shaped by the pandemic, how travellers view the future of tourism and how they are willing to contribute to potential changes. Furthermore, it examines the impact of socio-structural background factors, basic values and holiday preferences, and pandemic-related factors on the views of post-pandemic tourism.

Design/methodology/approach

A longitudinal online survey was conducted in which 155 frequent travellers were interviewed both before and during the pandemic about their values and holiday preferences, attitudes towards travelling during the pandemic, and their prospective views regarding tourism.

Findings

The findings revealed that values remained rather stable, but nature experiences, heritage tourism and beach offers gained more relevance when it came to holiday preferences. Concerning travellers’ expectations of future tourism, environmental concern was ranked higher than economic profit. However, those striving for self-direction, stimulation and city tourism offers stated to be less willing to restrict their travel behaviour in the future.

Research limitations/implications

Although our study is just based on a convenience sample, the authors were still able to address notable research gaps. First, because a longitudinal design was selected, it was possible to investigate any potential transitions in basic values and travel style and trace these changes back to the pandemic. Second, thanks to a sophisticated online survey, all concepts could be measured with well-developed scales, which increased the quality of the measurements and led to stable results. Third, young travellers can be considered proponents of future travel styles. Their way of acting and thinking about future tourism could significantly impact the prospective direction of tourism.

Practical implications

This study makes a valuable contribution to changing holiday preferences and provides useful insights for the tourism industry about travellers’ willingness to change their travel behaviour.

Social implications

Since this study primarily considers human values and socio-structural factors, the findings are of particular interest from a sociological perspective and are also interpreted from this viewpoint.

Originality/value

This study is one of only a few longitudinal studies focusing on holiday preferences and shifting values during COVID-19 and attempting to detect crucial drivers of potential tourism transformations in terms of perceptions from the demand side.

Abstract

Purpose

To investigate the effects of payor–provider integration on the operational performance of health service provision. The research explores whether integration governs agency problems and tilts the incentives of diverse actors toward more systematic outcomes.

Design/methodology/approach

A two stage multimethod case study of occupational health services. A qualitative stage aimed to understand the reasons, mechanisms, and outcomes of payor–provider integration. A quantitative stage evaluated the performance of the integrated hospital against fee-for-service partner hospitals with a sample of 2,726 patients.

Findings

Payor–provider integration mitigates agency problems on multiple levels of the service system by complementing formal governance mechanisms with informal mechanisms. Compared to partner hospitals, the integrated hospital yielded 9% lower the total costs of occupational injuries achieved primarily by emphasizing conservative care and faster recovery.

Research limitations/implications

Focuses on occupational health services in Finland. Provides initial evidence of the effects of payor–provider integration on the operational performance.

Practical implications

Vertical integration may provide systematic outcomes but requires mindful implementation of multiple mechanisms. Rigorous change management initiative is advised.

Social implications

For patients, the research shows payor–provider integration of health services can be implemented in a manner that it reduces care costs while not compromising care quality and customer satisfaction.

Originality/value

This study provides a rare longitudinal analysis of payor–provider integration in health-care operations management. The study adds to the knowledge of operational performance improvement of health services.

Abstract

Purpose

This paper brings focus and attention to the aspect of time within health information behaviour. The purpose of this paper is to critically assess and present strengths and weaknesses of utilising the infodemiology approach and metrics as a novel way to examine temporal variations and patterns of online health information behaviour. The approach is shortly exemplified by presenting empirical evidence for temporal patterns of health information behaviour on different time-scales.

Design/methodology/approach

A short review of online health information behaviour is presented and methodological barriers to studying the temporal nature of this behaviour are emphasised. To exemplify how the infodemiology approach and metrics can be utilised to examine temporal patterns, and to test the hypothesis of existing rhythmicity of health information behaviour, a brief analysis of longitudinal data from a large discussion forum is analysed.

Findings

Clear evidence of robust temporal patterns and variations of online health information behaviour are shown. The paper highlights that focussing on time and the question of when people engage in health information behaviour can have significant consequences.

Practical implications

Studying temporal patterns and trends for health information behaviour can help in creating optimal interventions and health promotion campaigns at optimal times. This can be highly beneficial for positive health outcomes.

Originality/value

A new methodological approach to study online health information behaviour from a temporal perspective, a phenomenon that has previously been neglected, is presented. Providing evidence for rhythmicity can complement existing epidemiological data for a more holistic picture of health and diseases, and their behavioural aspects.

Abstract

Purpose

The literature mainly concentrates on the relationships between externally oriented digital transformation (ExtDT), big data analytics capability (BDAC) and business model innovation (BMI) from an intra-organizational perspective. However, it is acknowledged that the external environment shapes the firm's strategy and affects innovation outcomes. Embracing an external environment perspective, the authors aim to fill this gap. The authors develop and test a moderated mediation model linking ExtDT to BMI. Drawing on the dynamic capabilities view, the authors' model posits that the effect of ExtDT on BMI is mediated by BDAC, while environmental hostility (EH) moderates these relationships.

Design/methodology/approach

The authors adopt a quantitative approach based on bootstrapped partial least square-path modeling (PLS-PM) to analyze a sample of 200 Italian data-driven SMEs.

Findings

The results highlight that ExtDT and BDAC positively affect BMI. The findings also indicate that ExtDT is an antecedent of BMI that is less disruptive than BDAC. The authors also obtain that ExtDT solely does not lead to BDAC. Interestingly, the effect of BDAC on BMI increases when EH moderates the relationship.

Originality/value

Analyzing the relationships between ExtDT, BDAC and BMI from an external environment perspective is an underexplored area of research. The authors contribute to this topic by evaluating how EH interacts with ExtDT and BDAC toward BMI.

Abstract

Purpose

No systematic review has previously been dedicated to comprehensively investigate predictors of well-being and ill-being in working contexts. Empirical studies have vastly associated well-being as the result of autonomous motivation and basic psychological needs satisfaction, while frustration results in ill-being. The purpose of this study is to integrate the variables identified in empirical studies associated with the occurrence of the phenomena, individual/organizational features and consequences associated with workers' well-being/ill-being.

Design/methodology/approach

This systematic review includes 44 empirical studies published up to February 2021. Findings are summarized based on quantitative analysis of the evidence.

Findings

Results reinforce the role of self-determined motivation and needs satisfaction in promoting well-being, while amotivation and needs frustration led to ill-being. Besides, they indicate that ill-being can both lead to negative consequences and diminish positive work outcomes. Findings also revealed that: integrated motivation does not seem to be empirically distinct from intrinsic and identified motivation in promoting well-being; introjected motivated behaviors may be less harmful to psychological health than externally oriented ones; the relationship between external motivation and well-being/ill-being requires prospective investigations; and amotivation seems to have a detrimental effect in workers' psychological health.

Practical implications

Results provide practical information for HRM practitioners to design work environments and practices that promote employees' psychological health.

Originality/value

An unprecedented framework that aggregates empirical findings regarding the antecedents, predictors and consequences of ill-being/well-being in working contexts is presented.

Abstract

Purpose

Alcohol, tobacco, marijuana and other drugs use typically increases in prevalence and frequency during middle and late adolescence. School health instruction often focusses on providing facts and rarely provides tools for addressing the psychosocial risk factors needed to prevent substance use. The purpose of this paper is to report about the effectiveness of a prevention programme delivered in US high school health classes. The intervention augments typical instruction by providing teachers with activities that can be infused in their daily teaching.

Design/methodology/approach

In total, 26 schools were randomly assigned to receive the intervention or serve as controls. Pupils were pretested near the beginning of the school year, posttest near the end of the school year and administered a final test near the beginning of the following school year. Teachers in treatment schools were provided with activities designed to target psychosocial variables known to mediate substance use onset and self-initiated cessation. These include normative beliefs, intentionality, lifestyle incongruence, beliefs about consequences of use, peer pressure resistance skills, decision-making skills, goal setting skills and stress management skills.

Findings

Hierarchical modelling analytic strategies revealed the intervention to have definable positive impacts on alcohol and cigarette use. Moreover, the intervention had strongest effects on alcohol and cigarette use among pupils who were identified at pretest as being lower-than-average risk.

Originality/value

This research provides support for providing teachers with a strategy for preventing alcohol, tobacco and other drugs that can be used in a flexible manner to augment the instruction they are already mandated to provide.
