The malleability of international entrepreneurial cognitions: a natural quasi-experimental study on voluntary and involuntary shocks
Authors: Clark Daniel R. , Pidduck Robert J. , Tietz Matthias A. 
Published: January 2022

PurposeThe authors investigate the durability of international entrepreneurial cognitions. Specifically, they examine how advanced business education and the Covid-19 pandemic influence international entrepreneurial orientation disposition (IEOD), and subsequently entrepreneurial intentions (EIs), to better understand the psychological dynamics underpinning the drivers of international entrepreneurship.Design/methodology/approachAgainst the backdrop of emerging entrepreneurial cognition and international entrepreneurial orientation research, the authors theorize that both a planned business education intervention (voluntary) and an unforeseeable radical environmental (involuntary) change constitute cognitive shocks impacting the disposition and intention to engage in entrepreneurial efforts. The authors use pre- and post-Covid-19 panel data (n = 233) and uniquely identify the idiosyncratic cognitive effects of Covid-19 through changes in the OCEAN personality assessment.FindingsFindings demonstrate that when individuals' perceived psychological impact of Covid-19 is low, business education increases IEOD. Conversely, the effects of a strongly perceived Covid-19 impact reduce the risk-taking and proactiveness components of the IEOD scale. The authors trace the same effects forward to EIs.Research limitations/implicationsThis paper contributes to a greater understanding of the resilience of entrepreneurial dispositions through an empirical test of the IEOD scale and shows its boundary conditions under planned intervention as well as unplanned externally induced shock.Practical implicationsThe study offers a first benchmark to practitioners of the malleability of international entrepreneurial dispositions and discusses the potential to encourage international entrepreneurial behaviour and the individual-level dispositional risk posed by exogenous shocks.Originality/valueThe study uniquely employs a baseline measure of all our constructs pre-Covid-19 to discern and isolate the pandemic impact on entrepreneurial dispositions and intentions, responding to recent calls for more experimental designs in entrepreneurship research.
Challenging Malawian primary teachers' views on mathematics teaching and learning through lesson study
Authors: Fauskanger Janne , Helgevold Nina , Kazima Mercy , Jakobsen Arne 
Published: January 2022

PurposeThe aim of the study is to better understand how lesson study (LS) contributes to challenging teachers' views of mathematics teaching and learning.Design/methodology/approachThis study is part of a wider ongoing project aiming at improving primary mathematics teaching in Malawi through professional development (PD) of teachers using a LS model. The units being analyzed are teachers' written reflections and lesson plans. The analytical approach is qualitative content analysis.FindingsInitially, the participating Malawian primary teachers report traditional views of mathematics teaching and learning. After having participated in a LS cycle, they reported on the need to work on how to involve and create space for learners' participation in mathematic lessons and highlight the importance for learners to discover mathematics on their own.Research limitations/implicationsThis is a small-scale study due to LS being quite new in the Malawian context and the need to test before possible upscaling.Practical implicationsThe paper includes a description on how LS might contribute to challenging Malawian teachers' views of mathematics teaching and learning; this can be valuable information for others who are attempting to use LS in a similar context.Originality/valueThis paper fulfills an identified need to learn more about how LS might contribute to challenging teachers' views of mathematics teaching and learning worldwide.
A categorisation of dialectics in response to project uncertainty
Authors: Buhagiar Michael , Pollack Julien , Coyle Sharon 
Published: January 2022

PurposeScholars are increasingly acknowledging the importance of conversations in the management of complex projects. Defining dialectics as “the art of purposeful conversation”, this paper aims to rationalise the somewhat disorganised field of dialectics by developing a categoreal scheme.Design/methodology/approachThe authors refer to the current state of research into the conversational aspects of complex projects, and examine the historical development of, and philosophical and scholarly commentary on, the dialectical method.FindingsThe categories the authors propose are the Socratic, Conversational, Fichtean and Peircean. They differ in relation to the subject matter of the dialectic; their vulnerability to environmental influences; the degree of structure they require for optimal performance; and the situations in which they might most profitably be applied.Research limitations/implicationsA single categoreal scheme is rarely the last word, and the authors invite other scholars to explore the field in a similar way.Practical implicationsThe scheme proposed here is intended to enhance the project manager's approach to conversations, by referring to the specific virtues and limitations of each of the categories.Social implicationsThe informed use of dialectics may help to ameliorate the significant damage done to organisations and economies around the world by failed and underperforming projects.Originality/valueThe authors present the first categorisation of the field, with the aim of equipping the practitioner to think about dialectical approaches in a more systematic way.
Land use and cover change (LUCC) and migration in Sukoharjo, Indonesia
Authors: Yogi Anang Pra , Samudro Bhimo Rizky , Soesilo Albertus Maqnus , Pratama Yogi Pasca 
Published: January 2022

Purpose
This study aims to provide descriptive analysis on urbanization pattern in Sukoharjo Regency and also its correlation to land use and cover change (LUCC) issue. This becomes more relevant because the authors find that there are few studies conducted regarding the topic. Consider again the importance role of Sukoharjo Regency as an area that provides supporting food supply, LUCC particularly in agriculture land became even more crucial.

Design/methodology/approach
This study uses literature reviews and descriptive analysis. Data for this study are obtained from previous studies and statistical data from Central Statistical Bureau.

Findings
Sukoharjo Regency proved as an interesting migration destination for some group of population. The population group particularly come from Surakarta city (growth core) as a form of urban sprawl or urban expansion. Migrant population live in Sukoharjo Regency are mostly a population group with a productive age range and generally with high-school or vocational school level. Moreover, their main reason to migrate is the availability of job opportunities. Regarding LUCC, migrant populations that come to Sukoharjo Regency apparently have property with ownership certification. Housing area development, particularly concentrated in the district, was located close to the borderline Surakarta city.

Originality/value
This research contributes to the analysis of land use change trends in peri-urban areas caused by migration. The results of this study can be used for further policy making to overcome the dilemma of land use change, especially those that occur on agricultural land.
Prioritization and ranking of lean practices: a case study
Authors: Sangwa Narpat Ram , Sangwan Kuldip Singh 
Published: January 2022

PurposeThe paper aims to identify, prioritize and rank lean practices in the context of an Indian automotive component manufacturing organization using interpretive ranking process (IRP) and interpretive structural modeling (ISM) approaches.Design/methodology/approachLean practices are identified from the literature. Then, two hierarchical models were are developed using two distinct modeling approaches – ISM and IRP with expert opinions from an Indian automotive component manufacturing organization to analyze the contextual relationships among the various lean practices and to prioritize and rank them with respect to performance dimensions.FindingsIn the study, the hierarchical structural models are developed using ISM and IRP approaches for an Indian automotive component manufacturing organization. In ISM-based modeling, lean practices can be categorized into five levels. Top priority should be given to the motivators followed by value chain, system/technology and organization centric practices. IRP model shows the dominance relationship among the various lean practices with respect to performance dimensions.Practical implicationsThe models are constructed from the organizational standpoint to evaluate their impact to the implementation of lean manufacturing. The study leverages the organizations to prioritize limited resources as per the hierarchy. Managers get the inter-linkages and ranking of various lean practices, which leads to a better perspective for the effective implementation of lean. The structural models also assist management to assign proper roles to employees/departments for effective lean implementation.Originality/valueThere is hardly any structural model of lean practices in the literature for clustering, prioritizing and ranking of lean practices. The study fills this gap and develops the hierarchical models of lean practices through IRP and ISM approaches for an Indian automotive component manufacturing organization. The results from both approaches are compared for illustrating the benefits of one over the other.
Design multivariate statistical process control procedure in the case of Ethio cement
Authors: Tegegne Daniel Ashagrie , Azene Daniel Kitaw , Atanaw Eshetie Berhan 
Published: January 2022

PurposeThis study aims to design a multivariate control chart that improves the applicability of the traditional Hotelling T2 chart. This new type of multivariate control chart displays sufficient information about the states and relationships of the variables in the production process. It is used to make better quality control decisions during the production process.Design/methodology/approachMultivariate data are collected at an equal time interval and are represented by nodes of the graph. The edges connecting the nodes represent the sequence of operation. Each node is plotted on the control chart based on their Hotelling T2 statistical distance. The changing behavior of each pair of input and output nodes is studied by the neural network. A case study from the cement industry is conducted to validate the control chart.FindingsThe finding of this paper is that the points and lines in the classic Hotelling T2 chart are effectively substituted by nodes and edges of the graph respectively. Nodes and edges have dimension and color and represent several attributes. As a result, this control chart displays much more information than the traditional Hotelling T2 control chart. The pattern of the plot represents whether the process is normal or not. The effect of the sequence of operation is visible in the control chart. The frequency of the happening of nodes is recognized by the size of nodes. The decision to change the product feature is assisted by finding the shortest path between nodes. Moreover, consecutive nodes have different behaviors, and that behavior change is recognized by neural network.Originality/valueModifying the classical Hotelling T2 control chart by integrating with the concept of graph theory and neural network is new of its kind.
Do professional courses prepare hospitality students for efficient surplus food management? A self-evaluation of professional competence in food waste prevention
Authors: Ko Wen-Hwa , Lu Min-Yen 
Published: January 2022

Purpose
This study aims to examine Taiwanese hospitality students’ self-reported professional competence in surplus food management and assess the usefulness of their university training in this area. Using the importance-performance analysis (IPA) method, it is possible to obtain a clearer understanding of the priority order of the items that require improvement and to identify which surplus food management competence items should be strengthened in the school curriculum and which items should be enhanced by the students.

Design/methodology/approach
This study used the questionnaire survey method. It evaluated seven dimensions covering 29 items related to surplus food management competencies of the kitchen staff. The evaluation was done using IPA to determine the relationship between professional competence (performance level) and courses provided (importance level). The factor coordinates were completed according to the means of personal qualifications and courses provided.

Findings
According to students’ self-assessment, the dimensions of “Personal moral attitude,” “Food handling attitude,” “Education and training attitude” and “Culinary knowledge” were located in the “Keep up the good work” quadrant, meaning that the students think that their surplus food management competence is relatively high and the courses provided are sufficient. Thus, these items have better performance at the present and they hope to maintain the status. However, “Menu analysis” and “Sanitation knowledge” were found to have low importance and low level of performance. Therefore, these two dimensions require attention in the course design and educational training.

Research limitations/implications
The questionnaire responses were self-reported; this study assumed that all participants answered honestly. Future studies may include additional factors in the analysis, such as hospitality management, culinary skills, internship experience and work time that may affect the perceptions of students. Moreover, professional chefs could be surveyed to determine their professional competence and training needs.

Originality/value
The professional training that students receive determines, to a large extent, their performance in their jobs and the resulting stability of their employment. Therefore, improved competence gained through good-quality training can help students meet the demands of the hospitality industry.
From success to unrest: the social impacts of tourism in Barcelona
Authors: Elorrieta Berezi , Cerdan Schwitzguébel Aurélie , Torres-Delgado Anna 
Published: January 2022

Purpose
This study aims to examine the main factors and the related impacts that have caused a negative shift in the social perception of tourism among residents of Barcelona. Namely, it contextualises the recent evolution of the impacts and the social perception of tourism among the city’s residents; analyses the relationship between the social perception of tourism and different tourist, real estate, demographic and economic factors; and lastly, it identifies the social impacts that majorly influence the negative perception among residents in every neighbourhood.

Design/methodology/approach
This study applies quantitative and qualitative techniques to a selection of five neighbourhoods of Barcelona. First, the character of the neighbourhoods was analysed, and external statistical information was later provided to understand the state and evolution of the factors that shape perceptions of tourism. Secondly, representatives of the community movements were interviewed in-depth. This consecutive qualitative approach enabled the comprehension of how these factors shape the residents’ perception.

Findings
The results showed that residents generally shared similar perceptions despite variations among neighbourhoods. Perceived negative effects included not only the most direct consequences of tourism such as anti-social behaviour and congestion of public spaces but also indirect ones such as population displacement and the weakening of social structures.

Originality/value
This study’s innovation lies in linking objective statistical data that describe the reality of a tourist neighbourhood (housing prices, number of available beds, family income, etc.), to the subjective perceptions of its residents. Thus, it is possible to identify the perceived impacts of tourism (which have an impact on the local population’s satisfaction), and relate these to the true evolution of tourism variables in the neighbourhood. This contrasted reading between perception and reality is important for future initiatives for the regulation of tourism in the city.
Can grassroots festivals serve as catalysts to connect and empower youth in urban informal settlements? A case study of art festivals in Indonesian kampungs
Authors: Akbar Poeti Nazura Gulfira 
Published: January 2022

Purpose
The purpose of this study is to examine how young residents in two Indonesian kampungs (urban informal settlements) participate in two grassroots art festivals and to what extent their participation affects their capacity and network.

Design/methodology/approach
This study uses a qualitative method. The data collection were done in 2017 and took the form of in-depth semi-structured interviews with 15 respondents in two kampungs, Kampung Dago Pojok, Bandung, and Kampung Bustaman, Semarang.

Findings
The results show that the grassroots festival can empower youth throughout its process while also influencing their networks. The festival could act as the catalyst for youth to gain event management skills and exchange cultural knowledge. This study also found that there are two sides the art festivals can bring to the youth regarding their network: while the festival was able to develop their internal and external network, it also led to social division within the community.

Originality/value
The originality of this paper lies in the context of the research where it contributes to understanding the implications of community-based art festivals in the developing context, particularly in the low-income informal settlements. The paper’s content also provides insights that festivals can also be understood as more than place marketing or branding but as collections of steps and efforts of the community to provide meaningful actions for their place and people.

Published: January 2022

Purpose
A parametric method for designing the hub, casing and blades of the miniature centrifugal compressor impeller was developed. The relationship model of the size, aerodynamic and performance parameters of the centrifugal impeller was established. Based on the selected design parameters, the miniature centrifugal-type impeller was designed, and the work efficiency was calculated.

Design/methodology/approach
In this study, a micro-centrifugal compressor impeller with a diameter of less than 25 mm was designed. A parametric design method was developed, and the functional relationship between the geometric and gas fluidity parameters was established.

Findings
The results of this study showed that the performance parameters of the designed micro-centrifugal impeller satisfied the design requirements. The proposed method is useful as a reference for designing and analysing compressor impellers under high Reynolds number conditions.

Originality/value
A parametric design method was developed, and the functional relationship between the geometric and gas fluidity parameters was established. Under the Reynolds number conditions, the flow characteristics of the gas in the compressor were analysed; the shear-stress transport turbulence equation was solved using the finite volume method. In addition, the effects of the Reynolds number on the velocity, pressure, mass flow and efficiency of the micro-scale centrifugal compressor were evaluated. The results showed that the performance parameters of the designed micro-centrifugal impeller satisfied the design requirements. The proposed method is useful as a reference for designing and analysing compressor impellers under high Reynolds number conditions.

Authors: Wang Juan , Huang Xiongrong , Wang Wei , Han Haosheng , Duan Hongyu , Yu Senlong , Zhu Meifang 
Published: January 2022

Purpose
The purpose of this study is to determine the tribological behavior and wear mechanism of a polytetrafluoroethylene (PTFE)/polyester (PET) fabric composite for application as a self-lubricating liner suitable for high-speed and low-load friction conditions.

Design/methodology/approach
The effects of different loads and sliding speeds on the friction coefficients and wear characteristics of the composite were studied using reciprocating friction tests. Scanning electron microscopy, extended depth-of-field microscopy, and energy-dispersive X-ray spectrometry was used to analyze the worn surface morphology, wear depth and elemental content of the lubrication films, respectively.

Findings
The friction coefficient curves of the composites presented a long-term steady wear stage under different sliding conditions. With increasing sliding speed, the friction coefficient and wear depth of the composite slowly increased. The film-forming mechanism of the composite revealed that the PTFE/PET ply yarn on the composite surface formed complete PTFE lubrication films at the initial sliding stage.

Originality/value
The PTFE/PET fabric composite maintained good friction stability and high-speed adaptability, which demonstrates that the composite has broad application prospects as a highly reliable self-lubricating bearing liner with a long lifespan.
