Control flow versus communication: comparing two approaches to process modelling
Authors: Moattar Haleh , Bandara Wasana , Kannengiesser Udo , Rosemann Michael 
Published: February 2022

PurposeBusiness process modelling integrates and visualizes relevant information essential for managing day-to-day business operations. It plays a critical role in the design and execution of business transformations. Recognizing the role of process modelling, a large number of modelling languages, methods and techniques have been developed, each offering diverse advantages and having inherent limitations. Traditional and popular process modelling approaches focus on the exact specification of the control flow of business processes, whereas more recent approaches like Subject-oriented Business Process Management (S-BPM) are focused on the communication between process participants. This study aims to provide comparative insights about these two approaches through their experimental application. This study does so by comparing Business Process Model and Notation (BPMN); a control flow approach, with S-BPM; a communication approach, with a specific focus on their suitability for novice modellers.Design/methodology/approachThis paper reports on an exploratory experiment that compares BPMN to S-BPM. Applying cognitive load theory, this study compares the experiences and outcomes of novice process modellers, assessing perceived ease of use, model quality (syntactic and semantic) and modelling efficiency (time to model) across the two approaches.FindingsStudy results show that S-BPM (a communication approach) led to significantly better user performances for process modelling than BPMN (a control flow approach). This study points to how a different modelling approach such as S-BPM could be either considered as an alternative or to complement the more popular control flow approach BPMN. This observation was especially relevant for modelling contexts where domain experts are novice process modellers.Originality/valueThis study provides the first empirical evidence that communication approaches like S-BPM could outperform modelling approaches which are control-flow based (i.e. BPMN), especially when being used by novice process modellers who hold the domain and process knowledge. This study uses this as a springboard to present important considerations for practice and guide future process modelling research.
Do political connections shape the nexus between board attributes and corporate cash holdings?
Authors: T.F. Abuhijleh Sara , A.A. Zaid Mohammad 
Published: February 2022

PurposeMotivated by the agency theory, this paper primarily intends to empirically investigate the impact of board attributes on corporate cash holdings and how the mentioned nexus is moderated by the level of corporate political connections in a developing country, namely, Palestine during the period of 2011–2018.Design/methodology/approachMultiple regression analysis on a panel data was employed. Moreover, the authors applied three different approaches of static panel data “pooled OLS, fixed effect and random effect”. Fixed-effects estimator was selected as the optimal and most appropriate model. In addition, to control for the potential endogeneity problem and to profoundly analyze the study data, the authors perform the one-step system generalized method of moment estimator.FindingsThe results of this study provide support for the agency theory ideology, which considers that sturdy and well-established corporate governance (CG) paradigms minify the magnitude of cash held by companies. Furthermore, the findings distinctly unveil that the impact of board attributes is more positive under a high level of political connections.Research limitations/implicationsThis study was solely restricted to one institutional context “Palestine”; therefore, the results reflect the attributes of the Palestinian business environment. In this vein, it is possible to generate different findings in other countries, particularly in developed markets.Practical implicationsThe findings of this study can draw responsible parties, top management and policymakers' attention in developing countries to introduce and contextualize new mechanisms that can lead to better managing of corporate cash holdings.Originality/valueEmpirical evidence on the moderating role of political connection on the effect of board attributes on corporate cash holdings something that was predominantly neglected by the earlier research and has not yet examined by ancestors. Hence, to protrude nuanced understanding of this novel idea, this study minutely bridges this research gap and contributes practically and theoretically to the existing CG–cash holdings literature.
A scientometric analysis and review of construction labour productivity research
Authors: Adebowale Oluseyi Julius , Agumba Justus Ngala 
Published: February 2022

PurposeLabour productivity in construction has fallen behind other industries in most of the world and has declined continuously for decades. Although several scholarly research projects have been conducted to salvage the prevalent low labour productivity in construction, contractors in the construction industry have continued to grapple with the devastating impact of low productivity. The purpose of this study is to determine key areas of focus necessary to promote productivity growth in construction.Design/methodology/approachBibliometric and scientometric assessments were conducted to map the existing construction labour productivity (CLP) studies and establish key focus areas in the research domain. The keywords “Construction Productivity” OR “Construction Labour Productivity” OR “Construction Labor Productivity” OR “Construction Worker Productivity”.FindingsEmerging trends in the CLP research field are reported. The study also determined the most productive authors and collaboration among authors, most productive journals, most active regions and publications with the highest impact in CLP research.Research limitations/implicationsDocuments published in the Scopus database were considered for analysis because of the wider coverage of the database. Journal and conference articles written in English language represent the inclusion criteria, while articles in press, review, book chapters, editorial, erratum, note, short survey and data paper were excluded from analysis. The study is also limited to documents published from 2012 to 2021.Practical implicationsThe study brought to the awareness of the industry practitioners and other construction stakeholders, the key knowledge areas that are critical to promoting productivity growth in construction.Originality/valueExcept bibliometric analysis, previous research studies have used different approaches to investigate productivity in construction. The study presented future research directions through the emerging knowledge areas identified in the study.
Piston ring performance II: measurement of cavitation shapes in different operating conditions and their link to lubricant properties
Authors: Dellis Polychronis Spyridon 
Published: February 2022

PurposeThis study aims to compare cavitation shapes between the simulating test rig and the engines to strengthen the findings that were first observed in the simplified experiments. Different forms of cavitation were identified, and their shape and size (length and width) were dictated from reciprocating speed and viscosity of the lubricant. Cavitation degrades performance in engineering applications and its effect is that it alters the oil film pressure.Design/methodology/approachLubricant formulations were used for parametric study as well as different operating testing parameters in a simulating test rig and single cylinder engines with visualisation windows. An algorithm was used for extracting cavitation data from imaging, and comparison was made.FindingsSimilar phenomena at the simulating test rig and the engine were investigated and compared. The effect of different operating conditions was assessed along with the variations produced from the parametric lubricant study.Research limitations/implicationsEngine results are limited due to manufacturing difficulties of visualisation windows and oil starvation. Firing tests are another difficult challenge as the modified section pressure is under more pressure and the window view is affected by combustion process. Limited pictures can be captured before cleaning is required. A lubricant manufacturer has to provide data regarding the chemistry of the lubricants.Originality/valueThe effect of cavitation in piston ring lubrication along with variable operating and lubricant parameters is further studied with quantification of cavitation results through image processing. These forms of cavities are affected by lubricant properties and operating conditions. A link between viscosity, cavitation, shear thinning properties, oil film thickness (OFT) and friction is given.
Employee ownership and firm R&D investment: evidence from China
Authors: Ren Ting , Xiao Youzhi , Pinto Daniel , Yang Hongyan 
Published: February 2022

PurposeAs majority of studies of employee ownership (EO) take place in developed markets and primarily focus on the impact on firm performance, scholars have recently called for other markets, especially large developing markets to be considered, as well as alternative outcome measures.Design/methodology/approachThrough the examination of the implementation of EO by Chinese listed firms during the period of 2011–2019 with total 3,473 firms and 21,204 observations, the authors provide empirical evidence on the positive effect of EO on firm R&D investment within the rapidly growing Chinese market.FindingsThe authors find that the adoption of EO promotes higher level of firm R&D investment. This positive relationship is more evident among small firms, non-state-owned firms and local state-owned-firms, compared with their counterparts. As for the plausible channels, the authors find that adopting EO provides a favorable institutional environment, which attracts more technical staff, improves workplace quality, and encourages job stability and greater employee effort, leading to greater R&D investment.Originality/valueThough the connection between R&D investment/innovation and firm survival performance has been known for decades, the innovation side of outcomes has been ignored by EO research. Therefore, the authors explore the relationship between EO implementation and firm R&D investment within the rapidly growing Chinese market.

Authors: Kumar Virendra , Paswan Rajesh Kumar 
Published: February 2022

Purpose
This paper attempted to study the alkali-activated (AA) binder consisting of 94% of ground granulated blast furnace slag (GGBFS) and 6% of blended powder of alkali metal hydroxide and metal sulfate, which acted as an activator.

Design/methodology/approach
Several concrete specimens (cubes, cylinders and prisms), which were casted using AA binders, were further tested for mechanical properties after exposure to elevated temperatures of 200 °C, 400 °C, 600 °C and 800 °C. Additionally, to understand the structural behavior in uniaxial compressive load, reinforced concrete short columns were cast, cured and tested at ambient temperature as well as after exposure to 300 °C, 600 °C and 900 °C, to know the residual strength after exposure to elevated temperature.

Findings
The findings for the residual strength of alkali-activated slag binder concrete (AASBC) indicated a substantial agreement with the results obtained for the residual strength of Portland slag cement (PSC) concrete, thereby showing the effectiveness of binder when used as a replacement of cement.

Originality/value
The study clearly indicates that the binder developed is an effective approach for the 100% replacement of cement in the concrete.
Transformations and appropriations of the in-between spaces in Cairo
Authors: Aboualy Sarah , Mansour Yasser , El-Fiki Sherif 
Published: February 2022

PurposeThe paper aims to study the applicability of Lefebvre's everyday life theory “production of space” in Sheraton's in-between spaces upon local residents' daily practices. Space as Lefebvre said is a result and cause, product and producer. Sheraton District, Cairo comprises lots of underutilized spaces between buildings. The in-between spaces have great potentials for accommodating diverse activities. The present study addresses the phenomenon of in-between spaces in this district. It is argued that in-between spaces can be developed to realize better functional and symbolic values, as the users attach special meanings based on users' everyday living.Design/methodology/approachThe study adopts a qualitative approach to investigate the above relationship on the mentioned district. The study devises direct observation to investigate people's behavioral patterns in such appropriated areas to analyze them in the light of preceding literature.FindingsThe study concludes that people's everyday practices could re-invent the in-between spaces by realizing new functions and meanings in dynamic and creative ways. That experience can apply to other underutilized spaces in the district and the city toward improving the built environment and the quality of residents' life.Research limitations/implicationsFinally, it is important to note that the findings of the study are limited to the studied context. Undertaking similar studies to other in-between spaces in Cairo, in other Egyptian cities or other countries may yield different findings. It may be equally interesting to study the means of adaptation in other underutilized urban spaces, such as those found underneath bridges, underneath buildings and on the rooftops.Originality/valueThe main aim of the present study is to examine the impact of everyday practices on the appropriation of a transformed in-between space in the aforementioned district, and the extent to which that may improve in-between spaces' role toward the local community, in order to promote such approach for developing many underutilized in-between spaces in the area. Toward realizing this goal, the study begins with a theoretical background about everyday life. Then, the paper addresses the theory of space appropriation. The outcome is then empirically investigated in relation to one transformed in-between space in Sheraton District, Cairo.
Modelling the interaction between serious leisure, self-perceived employability, stress, and workplace well-being: empirical insights from graduates in India
Authors: Nimmi P.M. , Donald William E. 
Published: February 2022

PurposeDrawing on a framework of Job Demands-Resources (JD-R), the purpose of this paper is to conceptually develop and empirically validate a moderated mediation model of serious leisure and workplace well-being.Design/methodology/approachThe data were collected between December 2020 and March 2021 using an online questionnaire. A total of 225 completed questionnaires were received from employees in India who graduated between 2018 and 2020.FindingsThe authors’ findings indicate that serious leisure is positively associated with workplace well-being and that the relationship is mediated by self-perceived employability. Stress moderates the relationship between serious leisure and self-perceived employability in such a way that the association is stronger when levels of stress are higher. Stress also moderates the mediating effect of self-perceived employability on the relationship between serious leisure and workplace well-being such that the indirect effect of serious leisure on workplace well-being is stronger when levels of stress are higher.Originality/valueTheoretical implications come from drawing on leisure studies literature to differentiate casual leisure and serious leisure. The concept of serious leisure is subsequently integrated into the human resource management literature to explore the relationship between serious leisure, self-perceived employability, stress, and workplace well-being. Practical and policy implications suggest how universities and organisations can support their students and early careers talent by encouraging them to participate in serious leisure activities.
The artist and the photograph: a semiotic analysis of consumers’ experiences with photographs
Authors: Plakoyiannaki Emmanuella , Stavraki Georgia , Tsapi Vasiliki 
Published: February 2022

Purpose
This study aims to address research calls to investigate how (visual) consumption experiences carry and convey meanings to individuals. Applying McCracken’s meaning transfer model to a photographic exhibition, the authors expand this model into the realm of aesthetic experiences to explore how the meaning of such an (visual) experience emerges and flows to (novice and expert) consumers.

Design/methodology/approach
This research uses an interpretive case study of the photographic exhibition “Facing Mirrors” hosted as part of the Biennale of Contemporary Art, and draws on multiple sources of evidence, notably 50 in-depth visitor interviews, observation and archival records.

Findings
The evidence highlights the moveable nature of meaning within an aesthetic context and illustrates the critical role of semiotics and of the different ritualistic behaviors enacted by novice and expert visitors as a means of unfolding and creating the meaning of such an experience.

Research limitations/implications
The findings provide implications in terms of (co-)creating authentic, immersive and meaningful (brand) experiences in the fields of visual consumption and customer experience management.

Practical implications
Practical implications to arts organizations are also provided in terms of curatorial practices that emphasize the material, emotional and dialogic nature of photographs as a visual art form.

Originality/value
The study provides new insights into (visual) consumption experiences by bringing the meaning transfer model together with a semiotic approach, thus illustrating different performances and sense-making activities through which (expert and novice) visitors (co-)create and appropriate the value of their aesthetic experiences.
Unboxing the therapeutic community for addictions: a locus-of-hope theory perspective
Authors: Ramos Sixtus Dane Asuncion , Bernardo Allan B. I. 
Published: February 2022

Purpose
The therapeutic community (TC) is a widely used treatment approach for substance use disorders. Several psychological theories have been used to explain its processes but have put less emphasis on the specific contributions of the person’s cognitive resources. This paper aims to offer a theoretical conceptualization using the locus-of-hope theory which expounds on the person’s goal-directed thinking and how it bolsters the TC process.

Design/methodology/approach
This paper reviewed contemporary theoretical perspectives on TCs and studies on locus-of-hope theory to provide arguments for locus-of-hope’s utility in understanding TCs. From this review, this paper discusses a formal conceptualization of TCs using the locus-of-hope model.

Findings
In this conceptualization, the authors explained that the TC becomes a co-agent in the person’s goal-pursuit by strengthening the individual’s beliefs regarding one’s capability to develop goals together with the will and strategies to attain these important recovery goals. The person’s hopeful thinking boosts the TC protocols in a dynamic fashion.

Originality/value
This paper offers a locus-of-hope perspective that considers the person’s contributions in bolstering the TC process. Reflections on clinical and research implications were provided. This paper aids further in unboxing of the TC.
Fine‐tuned spatiotemporal dynamics of sporophylls in movement‐assisted dichogamy: A study on Clerodendrum infortunatum
Authors: Mukhopadhyay Amritendu , Quader Suhel 
Published: February 2022

AbstractHermaphroditism is cost‐effective because a common investment in reward and attractive structures yields benefits through both male and female reproductive success. However, the advantage is accompanied by an increased risk of self‐pollen deposition, which is generally disadvantageous. Hermaphroditic plants reduce self‐pollen deposition by separating sporophylls (a term applied to the stamens and carpels) either spatially (herkogamy) or temporally (dichogamy). In movement‐assisted dichogamy, both sporophylls show coordinated motion in opposite directions. However, the effectiveness of this movement in reducing self‐pollen deposition may be compromised at the point when the sporophylls cross each other and are close enough to interfere, resulting in a transition phase problem. The solution to this problem lies in the details of the spatiotemporal dynamics of the sporophylls in relation to their reproductive maturity. We studied these details across the floral lifetime of a protandrous shrub, Clerodendrum infortunatum (Lamiaceae), in rainforest fragments of the Western Ghats, India. We took photos of flowers at regular time intervals and measured sporophyll angles from the images. We also carried out a field experiment to determine stigma receptivity. We found that the stigma lobes remained narrowly opened at transition, and the stigma surfaces remained non‐receptive. Our findings suggest that the effectiveness of dichogamy is maximized through two properties of the transition phase: physical resistance to self‐pollen deposition by narrow stigma lobe opening and chemical non‐receptivity of the stigma during this phase. This study emphasizes the importance of accessory adaptations in movement‐assisted dichogamy to tackle the transition phase problem.
Repeated exposure of fluazinam fungicides affects gene expression profiles yet carries no costs on a nontarget pest

Published: February 2022

AbstractFungicides are used to control pathogenic fungi of crop species, but they have also been shown to alter behavioral, life history and fitness related traits of nontarget insects. Here, we tested the fungicide effects on feeding behavior, survival and physiology of the nontarget pest insect, the Colorado potato beetle (CPB) (Leptinotarsa decemlineata). Feeding behavior was studied by a choice test of adult beetles, which were allowed to choose between a control and a fungicide (fluazinam) treated potato leaf. Larval survival was recorded after 24 and 72 h exposure to control and fungicide‐treated leaves with 2 different concentrations. The adults did not show fungicide avoidance behavior. Similarly, survival of the larvae was not affected by the exposure to fungicides. Finally, to understand the effects of fungicides at the physiological level (gene expression), we tested whether the larval exposure to fungicide alter the expression of 5 metabolic pathway and stress associated genes. Highest concentration and 72‐h exposure caused upregulation of 1 cytochrome P450 (CYP9Z14v2) and 1 insecticide resistance gene (Ldace1), whereas metabolic detoxification gene (Ugt1) was downregulated. At 24‐h exposure, highest concentration caused downregulation of another common detoxification gene (Gs), while both exposure times to lowest concentration caused upregulation of the Hsp70 stress tolerance gene. Despite these overall effects, there was a considerable amount of variation among different families in the gene expression levels. Even though the behavioral effects of the fungicide treatments were minor, the expression level differences of the studied genes indicate changes on the metabolic detoxifications and stress‐related pathways.
