Abstract
Purpose
The purpose of this paper is to propose a bicriteria integer programming model for hierarchical workforce scheduling in which the first criterion is the cost and the second is the suitability of task assignment to individual employees. The model is based on the integer programming formulation for the hierarchical workforce scheduling problem published in 2007 by Seçkiner et al., which extends the model proposed by Billionnet in 1999.
Design/methodology/approach
The principal hypothesis of this paper is that, although an employee is capable of performing several different tasks with equal efficiency, the type of task to which he/she is assigned affects the overall suitability of the assignment configuration. Therefore, cost‐minimising solutions should also optimise task assignment when possible. This paper considers real cases and confirm that this approach to the problem is appropriate for dealing with common situations in personnel management.
Findings
The proposed idea is applied to the example problem used by Seçkiner et al. and the results are compared with Seçkiner et al.'s model results.
Originality/value
Consequently, the proposal is more general and a more faithful representation of the problems faced by personnel managers, which should help to bridge the gap between academic studies and practical cases.

Abstract
Purpose
Simple assembly line balancing problem type 1 is the most studied assembly line problem and many procedures have been proposed to solve it. Ho and Emrouznejad proposed to add a novel set of constrains into a binary integer‐programming model that is useful for breaking symmetries between equivalent solutions. The purpose of this paper is to compare this way of breaking symmetries with the usual ones existing in the literature (by means of the objective function and by means of additional constraints) and propose two novel ways of breaking symmetries which improve the existing ones.
Design/methodology/approach
For the comparison, the authors solve the well‐known benchmark instances.
Findings
It was found that the most efficient model is one of the new models which has not been proposed in the literature to date. Moreover, the authors noticed that Ho and Emrouznejad attribute a mathematical model to Patterson and Albracht that is different from the original model proposed by Patterson and Albracht.
Originality/value
There is not, in the literature, a comparison between classical and new mathematical models. The authors give an empirical comparison between them, together with two new ones that the authors propose. Moreover, the authors point out the mistake about the attribution model in Ho and Emrouznejad's, work attributing a mathematical model to Patterson and Albracht, with the aim of preventing its possible propagation in future researches.

Abstract
Purpose
The purpose of this study is use a bibliometric analysis to explore the relational nature of knowledge creation in WFM in operations. Companies live under constant pressure to find the best ways to plan their workforce, and the workforce emangement (WFM) is one of the biggest challenges faced by managers. Relevant research on WFM in operations has been published in a several range of journals that vary in their scope and readership, and thus the academic contribution to the topic remains largely fragmented.
Design/methodology/approach
To address this gap, this review aims to map research on WFM in operations to understand where it comes from and where it is going and, therefore, provides opportunities for future work. This study combined two bibliometric approaches with manual document coding to examine the literature corpus of WFM in operations to draw a holistic picture of its different aspects.
Findings
Content and thematic analysis of the seminal studies resulted in the extraction of three key research themes: workforce cross-training, planning workforce mixed methods and individual workforce characteristics. The findings of this study further highlight the gaps in the WFM in operations literature and raise some research questions that warrant further academic investigation in the future.
Originality/value
Likewise, this study has important implications for practitioners who are likely to benefit from a holistic understanding of the different aspects of WFM in operations.

Abstract
The present study increases our understanding of strong power in exchange networks by examining its incidence in complex networks for the first time and relating this incidence to characteristics of these networks. A theoretical analysis based on network exchange theory (e.g., Willer, 1999) suggests two network characteristics predicting strong power; actors with only one potential exchange partner, and the absence of triangles, that is, one's potential exchange partners are not each other's partners. Different large-scale structures such as trees, small worlds, buyer–seller, uniform, and scale-free networks are shown to differ in these two characteristics and are therefore predicted to differ with respect to the incidence of strong power. The theoretical results and those obtained by simulating networks up to size 144 show that the incidence of strong power mainly depends on the density of the network. For high density no strong power is observed in all but buyer–seller networks, whereas for low density strong power is frequent but dependent on the large-scale structure and the two aforementioned network characteristics.

Abstract
Overtourism is an emerging concept and a perennial process every destination is going through. It is a cyclic phenomenon derived from the destination, retained in the destination and at last demised by the destination. It's a kind of ‘tourism illness’ spreading rapidly in every destination in the present scenario. The status of overtourism in every destination has been caused by the tourist, of the tourist and for the tourist. In the context of religious places in Odisha, overtourism is a ‘disorder’ that cannot be mitigated, as religiosity, faith and spiritualism have propelled and governed people's sentiment and emotion. Hence ambiguity arises out of making an intrigue situation between a myth or a spiritual sojourn bounded by faith and belief. This chapter significantly contributes by unfolding the existing literature by providing the origin and evolution of overtourism, various stated definitions by the different authors, causes and consequences, and overtourism in religious destinations by adopting an exploratory study, particularly in case of the Golden triangle of Odisha.

Abstract
Purpose
Current college students in the USA are reporting higher levels of anxiety over career planning than previous generations, placing pressure on colleges to provide effective career development opportunities for their students. Research has consistently found that increasing career-related self-efficacy is particularly effective at increasing career-related behaviors among college students. These studies, however, do not account for the potentially negative impact of anxiety on cognitive, mediational pathways, including self-efficacy. Therefore, the purpose of this paper is to determine if anxiety plays a sequentially mediating role in the relationship between self-efficacy and job search intentions among college students.
Design/methodology/approach
Participants who were currently looking for a job or an internship were recruited to participate in an online study regarding career development preparation. Participants completed a job search behaviors “quiz” and were randomly assigned to either a “no feedback/control” condition or a “false-positive feedback/experimental” condition. Their career decision-making self-efficacy and state-trait anxiety were then assessed, as well as their intentions to engage in job search behaviors. A sequential mediational pathway analysis was performed to determine whether anxiety plays a mediational role in the relationship between self-efficacy and job search behaviors.
Findings
The hypothesized sequential mediational model was statistically significant. More specifically, participants who were randomly assigned to receive positive feedback experienced significantly lower levels of anxiety than participants in the control condition. In turn, lower levels of anxiety led to significantly higher levels of self-efficacy and significantly higher levels of job search intentions.
Practical implications
These findings have immediate implications for practitioners and educators who work with college students or any population that may be facing anxiety regarding the job search process. More specifically, these underscore the importance of lowering anxiety in order to lead to significantly higher levels of engagement in the career preparation process.
Originality/value
Currently, few studies (if any) have examined the potential mediating impact of anxiety on career-related self-efficacy and career development. Furthermore, no study has incorporated experimental methodology to test multiple pathways between anxiety, self-efficacy, and career preparation.

Abstract
Purpose
This study aims to conduct a bibliometric analysis of sustainable tourism research published in Scopus-indexed journals covering the period from 1997 to 2021. Articles published during these 25 years were subjected to science mapping and performance analysis to propose potential areas for future research.
Design/methodology/approach
A bibliometric analysis using performance analysis and science mapping was conducted on 1,754 research papers retrieved from the Scopus database using the keyword “sustainable tourism.” Biblioshiny and VOSviewer are commonly used bibliometric tools. Science mapping techniques use coauthorship, keyword co-occurrence and co-citation analyses.
Findings
This study revealed the sustainable tourism publications’ spatial and temporal patterns, indicating a yearly growth rate of 19.9% during a 25-year period. The study identified Stefan Gossling as the most influential author, the “Journal of Sustainable Tourism” as the leading journal and Australia as the most productive country in sustainable tourism literature. The study used co-citation analysis to identify five thematic clusters, namely, reconceptualization and criticism, the role of residents, eco-labeling and the role of stakeholders, community-based tourism and the shift toward establishing sustainability indicators and effective governance and policymaking. The coauthorship analysis identifies the most influential author in collaborative efforts, and the most common pattern of collaboration is between researchers from different institutions in the same country, such as China and the Philippines, followed by collaborations between authors from other countries. The keyword co-occurrence analysis uncovered keywords that aligned with theme clusters generated from the co-citation analysis.
Originality/value
This study comprehensively uncovers five thematic clusters that have never been extracted so far in the literature. Also, it attempts to fill the gaps related to sustainable tourism by suggesting directions for future research.

Abstract
Purpose
The purpose of this study is to provide a series of indicators to determine the limits to urban tourism growth, tourism gentrification and overtourism. The study addresses overtourism within the frame of urban liveability through a proxy analysis of tourism-relevant indicators for major European tourist cities.
Design/methodology/approach
Based on the various indicators, a composite overtourism indicator is derived. The following dimensions are considered for the composite indicator: total number of overnight stays per relevant tourist area in km2; number of museum visitors per population; average annual change in total nights between 2009 and 2017; and foreign nights per population.
Findings
Based on the results, Venice is the city with the highest degree of overtourism, followed by Florence, Seville and Lisbon. The remaining cities have a lower than average overtourism potential as indicated by the negative z-score.
Research limitations/implications
This study and the composite overtourism indicators are only a starting point that can lead to further research in the field. Recommendations for further studies include the assessment of visitor flow and overtourism at different times of the year and to expand the study to other European urban destinations.
Practical implications
The paper suggests that policymakers should use these indicators when managing urban tourism development and monitoring visitor growth. Furthermore, they can be a starting point from which to assess the impact of tourism on the quality of life of local residents.
Social implications
This study provides a starting point from which to assess the causes for social unrest tied to overtourism. If the city under study is found to have a lower than average overtourism potential, this indicates that there may be other social or psychological issues at play apart from sheer overcrowding.
Originality/value
To date, there has been no composite indicator that considered the different numerical aspects of overtourism altogether. This study provides a set of key indicators and a composite overtourism indicator to provide a preliminary appraisal of overtourism as a demand-side phenomenon with evidence from a range of established European urban destinations.
