Evaluation and decision-making framework for concrete surface quality based on computer vision and ontology
Authors: Chai Ying Tao , Wang Ting-Kwei 
Published: July 2022

PurposeDefects in concrete surfaces are inevitably recurring during construction, which needs to be checked and accepted during construction and completion. Traditional manual inspection of surface defects requires inspectors to judge, evaluate and make decisions, which requires sufficient experience and is time-consuming and labor-intensive, and the expertise cannot be effectively preserved and transferred. In addition, the evaluation standards of different inspectors are not identical, which may lead to cause discrepancies in inspection results. Although computer vision can achieve defect recognition, there is a gap between the low-level semantics acquired by computer vision and the high-level semantics that humans understand from images. Therefore, computer vision and ontology are combined to achieve intelligent evaluation and decision-making and to bridge the above gap.Design/methodology/approachCombining ontology and computer vision, this paper establishes an evaluation and decision-making framework for concrete surface quality. By establishing concrete surface quality ontology model and defect identification quantification model, ontology reasoning technology is used to realize concrete surface quality evaluation and decision-making.FindingsComputer vision can identify and quantify defects, obtain low-level image semantics, and ontology can structurally express expert knowledge in the field of defects. This proposed framework can automatically identify and quantify defects, and infer the causes, responsibility, severity and repair methods of defects. Through case analysis of various scenarios, the proposed evaluation and decision-making framework is feasible.Originality/valueThis paper establishes an evaluation and decision-making framework for concrete surface quality, so as to improve the standardization and intelligence of surface defect inspection and potentially provide reusable knowledge for inspecting concrete surface quality. The research results in this paper can be used to detect the concrete surface quality, reduce the subjectivity of evaluation and improve the inspection efficiency. In addition, the proposed framework enriches the application scenarios of ontology and computer vision, and to a certain extent bridges the gap between the image features extracted by computer vision and the information that people obtain from images.
Beyond competing for talent: an integrative framework for coopetition in talent management in SMEs
Authors: Jooss Stefan , Lenz Julia , Burbach Ralf 
Published: July 2022

Purpose
This paper aims to unpack how small and medium-sized enterprises (SMEs) can operationalise coopetition in talent management, addressing ongoing talent shortages in the hospitality industry which were intensified during the Covid-19 pandemic.

Design/methodology/approach
This conceptual paper draws from literature on coopetition and talent management in SMEs. Specifically, the authors take an interorganisational talent pool lens and develop a framework following the principles of open-systems theory.

Findings
The authors find that the traditional use of talent pools is often impractical for SMEs because of a lack of resources and capabilities. Instead, interorganisational talent pools, through coopetition in talent management, can aid these firms to address talent shortages. The authors identify potential for SME coopetition at various stages, including attraction, development and retention of talent.

Practical implications
Coopetition in talent management can aid industries in establishing market-thickening pipelines. Through co-attracting, co-developing and co-retaining talent, SMEs can create interorganisational talent pools. To develop talent management coopetition, a set of prerequisites, catalysts and potential inhibitors must be analysed and managed.

Originality/value
This paper moves the talent management debate beyond competition for talent, introducing coopetition as a viable alternative. Taking an open-systems perspective, the authors develop an integrative framework for coopetition in talent management in SMEs encompassing input, process and output components. The authors reveal the dynamic and complex nature of this coopetition process, highlighting the essential role of coopetition context and illustrating open-system principles.

Published: July 2022

PurposeThe present study investigates the predicting role of institutional leadership competencies (namely, achieving goals and outcomes, leadership and leading change, and integrity and justice) in influencing job performance. It also seeks to examine whether proactive personality moderates the purported relationship.Design/methodology/approachData were collected from 103 institutional leaders in various higher education institutions in Malaysia. Partial least squares structural equation modeling (PLS-SEM) technique via Smart PLS 2.0 was used to analyze the data and test the hypotheses.FindingsThe findings indicate that competencies of leadership and leading change and integrity and justice significantly and positively influenced job performance. Proactive personality was found to significantly moderate the relationship between leadership and leading change dimension and job performance.Research limitations/implicationsThis study contributes to the literature by assessing leadership competencies as the predictors of job performance. The moderating role of proactive personality is also substantiated in the leadership and leading change dimension and job performance linkage.Practical implicationsThe significant and positive impact of leadership and leading change as well as integrity and justice on job performance suggests the importance of these leadership competencies in promoting high level of job performance among institutional leaders. Furthermore, in ensuring high job performance among institutional leaders, proactive personality is a crucial attribute that is worth to be given attention by higher education institution (HEI) administrators.Originality/valueThis study aims to provide additional empirical evidence in the leadership competencies domain. The research framework of this study managed to substantiate empirical evidence in partial support on the importance of leadership competencies and proactive personality in predicting job performance.
Fatigue damage indicator of different types of reinforcing bars
Authors: Koulouris Konstantinos F. , Apostolopoulos Charis 
Published: July 2022

PurposeAs it is widely known, corrosion constitutes a major deterioration factor for reinforced concrete (RC) structures which are located on coastal areas. This phenomenon combined with repeated loads, as earthquake events, negatively affects their service life. Moreover, microstructure of steel reinforcing bars has significant impact either on their corrosion resistance or on their fatigue life.Design/methodology/approachIn the present manuscript an effort has been made to investigate the effect of corrosive factor on fatigue response for two types of steel reinforcement; Tempcore steel reinforcing bars and a new generation dual phase (DP) steel reinforcement.FindingsThe findings of this experimental study showed that DP steel reinforcement led to better results regarding its capacity to bear repeated loads to satisfactory degree after corrosion, although this type of steel has less stringent mechanical properties.Originality/valueAdditionally, a fatigue damage material indicator is proposed as a parameter that could rank material quality and its suitability for a certain application. The results of this investigation showed that the fatigue damage indicator can be used as an appropriate index in order to evaluate the overall performance of materials, in terms of strength and ductility capacity.
The technical matters: young children debugging (with) tangible coding toys
Authors: Silvis Deborah , Lee Victor R. , Clarke-Midura Jody , Shumway Jessica F. 
Published: July 2022

Purpose
Much remains unknown about how young children orient to computational objects and how we as learning scientists can orient to young children as computational thinkers. While some research exists on how children learn programming, very little has been written about how they learn the technical skills needed to operate technologies or to fix breakdowns that occur in the code or the machine. The purpose of this study is to explore how children perform technical knowledge in tangible programming environments.

Design/methodology/approach
The current study examines the organization of young children’s technical knowledge in the context of a design-based study of Kindergarteners learning to code using robot coding toys, where groups of children collaboratively debugged programs. The authors conducted iterative rounds of qualitative coding of video recordings in kindergarten classrooms and interaction analysis of children using coding robots.

Findings
The authors found that as children repaired bugs at the level of the program and at the level of the physical apparatus, they were performing essential technical knowledge; the authors focus on how demonstrating technical knowledge was organized pedagogically and collectively achieved.

Originality/value
Drawing broadly from studies of the social organization of technical work in professional settings, we argue that technical knowledge is easy to overlook but essential for learning to repair programs. The authors suggest how tangible programming environments represent pedagogically important contexts for dis-embedding young children’s essential technical knowledge from the more abstract knowledge of programming.
How indigenous entrepreneurs negotiate cultural and commercial imperatives: insights from Aotearoa New Zealand
Authors: Manganda Admiral Munyaradzi , Mika Jason Paul , Jurado Tanya , Palmer Farah Rangikoepa 
Published: July 2022

Purpose
This paper aims to explore how Maori entrepreneurs in Aotearoa New Zealand negotiate cultural and commercial imperatives in their entrepreneurial practice. Culture is integral to Indigenous entrepreneurship, an example being tikanga Maori (Maori cultural values) and Maori entrepreneurship. This study discusses the tensions and synergies inherent in the negotiation of seemingly conflicting imperatives both theoretically and practically.

Design/methodology/approach
This study reports on a thematic analysis of semi-structured interviews involving ten Maori enterprises of the Ngati Porou tribe on the east coast of Aotearoa New Zealand.

Findings
This study finds that depending on their contextual and cultural orientation, Maori entrepreneurs use tikanga to help negotiate cultural and commercial imperatives. The contingency of entrepreneurial situations and the heterogeneity of Maori perspectives on whether (and in what way) tikanga influences entrepreneurial practice appear influential. The authors propose a typology of Maori entrepreneurs’ approaches to explain the negotiation of cultural and commercial imperatives comprising the “culturally engaged Maori entrepreneur”; the “culturally responsive Maori entrepreneur”; and the “culturally ambivalent Maori entrepreneur.”

Originality/value
This study proposes a typology to analyse entrepreneurial practices of Indigenous entrepreneurs’ negotiation of cultural and commercial imperatives.
Uncertainty in illness among individuals with schizophrenia: a phenomenology study in Indonesia
Authors: Irawani Fardelyn Hacky , Asniar Asniar , Marthoenis Marthoenis 
Published: July 2022

Purpose
Individuals with schizophrenia experience uncertainty due to the unpredictable symptoms, the course of the illness and poor knowledge about the disease, treatment and prognosis. Uncertainty in illness is linked with poor treatment outcomes, coping strategies, check-up decisions and psychological distress. This study aims to explore the uncertainty in illness among individuals with schizophrenia.

Design/methodology/approach
Eight individuals with schizophrenia living in the community were interviewed regarding their illness. The phenomenology approach was used to collect and analyze the data.

Findings
Three themes emerged from the findings of the study; the unpredictable course of the illness, compliance amid uncertainty and uncertainty of information about their illness. This study provides an essential overview of how patients with schizophrenia live in uncertain conditions.

Originality/value
It should be considered by various parties, particularly the community mental health nurses working with individuals with schizophrenia. Considering the uncertainty of illness while looking after or interacting with patients and their family is significant in improving adequate mental health-care delivery.

Published: July 2022

Purpose
This study aims to identify and explore experiences, perspectives, barriers and enablers to women’s career progression to management positions in the health-care sector and to assess women’s and men’s perceptions of the policies and practices of the health-care system concerning gender equality and nondiscrimination between women and men.

Design/methodology/approach
A cross-sectional survey was conducted among health-care professionals in ten selected hospitals, including physicians, registered nurses/midwives and pharmacists with or without managerial positions.

Findings
This study included a total of 2,082 female and 1,100 male health-care professionals. Overall, 70% of women and men reported that opportunities for advancement are based on knowledge and skills in their institution. However, 58.9% of women (p < 0.001) reported that women are more likely to face barriers to career advancement than men do in their workplace. Lack of women in general/line management and discrimination against women by supervisors at the point of promotion were the main barriers to women's career progression, as they were reported by two-thirds of women. The main barrier, as perceived by men (62.3%) was that women have family and domestic responsibilities.

Practical implications
To overcome barriers in women's career progression, there is a need to establish a career planning and capacity-building program for women in the health sector.

Originality/value
Jordanian female health-care professionals face different barriers that affect their career progression, including inequity and discrimination in the workplace, negative views about women’s abilities, lack of qualifications and training, hostile cultural beliefs and family responsibilities.
Quantifying the energy trilemma in China and assessing its nexus with smart transportation
Authors: Zhao Congyu , Dong Xiucheng , Dong Kangyin 
Published: July 2022

Purpose
Mitigating the energy trilemma (ET) is of great importance for dealing with climate change and realizing carbon neutrality. To this end, effectively assessing the level of the ET is essential. The purpose of this study is to evaluate the current situation and the spatio-temporal changes of the ET in the whole of China.

Design/methodology/approach
Moreover, based on provincial-level data in China for the period 2002–2017, and by using the dynamic estimation model, we aim to determine the specific marginal impacts of smart transportation (ST) on the ET, and the possible channels through which ST works on the ET.

Findings
We thus present the following findings: (1) The performance of both ET and its three pillars is gradually improving in China. Moreover, the situation tends to vary dramatically among various regions and provinces, and the gap between the best performers and the worst is large. (2) ST plays a significant role in inhibiting the ET, a finding that remains robust after a series of tests. And (3) the ET eradication effect of ST is caused mainly by improved innovation, advanced technical efficiency, and the increasing energy scale.

Originality/value
Accordingly, we put forward some policy recommendations to help tackle ET and accelerate ST in China.
Project fuzziness to project value: the role of social capital
Authors: Sharari Hakem , Paton Robert A. , Smart Alison 
Published: July 2022

Purpose
Project management scholars and practitioners have long debated how best to harness social interactions to optimise knowledge exchange and enhance stakeholder alignment and value. This study aims to assist project managers to understand and manage fuzziness and create enduring front-end value. It views the project life cycle as a potential source of co-created value. The paper uses a social capital lens to provide a deeper understanding of the project front-end; it uses a three-dimensional view (structural, relational, cognitive) to explore how stakeholder social capital can overcome front-end fuzziness to enhance decision-making and, thus, value creation.

Design/methodology/approach
Semi-structured interviews were conducted with senior managers from teleconnections companies, which, when combined with secondary data, established the impact, nature and dimensions of social capital within a project management setting.

Findings
The research found that social capital can help to reduce complexity, uncertainty and equivocality in the early stages of projects, making them more clearly defined and thus helping to create greater stakeholder value in the later stages of the project. A surprising finding was that some project team members engaged in intentional equivocality to try to promote their own benefits rather than those of the organisation.

Originality/value
This paper reconceptualises the impact of social capital on stakeholder value creation in the front-end of projects. The paper contributes to a more holistic view of the front-end of project management, focusing social capital to reduce the sources of front-end fuzziness.
Impact of JAK/STAT inhibitors on human monocyte‐derived‐macrophages stimulated by cigarette smoke extract and lipopolysaccharide

Published: July 2022

AbstractThe main risk factor for chronic obstructive pulmonary disease (COPD) is cigarette smoke (CS). It can alter many immune cells functions such as phagocytosis, efferocytosis and cytokine production. Cytokines play a role in the orchestration of inflammation in COPD. The JAK/STAT pathways are among the most important signalling components of cytokines. The objective of this work was to investigate the role of the JAK/STAT pathway with regard to cytokine release and microsphere uptake capacity (to minimize the non‐specific scavenging) in human monocyte‐derived‐macrophages (MDMs). The MDMs were stimulated by cigarette smoke extract (CSE) alone or in combination with lipopolysaccharide (LPS). CSE alone was not associated with significant changes in the cytokine, with the exception of IL‐8/CXCL8 production. However, CSE disturbed cytokine production in LPS‐stimulated MDMs. CSE increase CXCL‐8 and CCL2 release in LPS‐stimulated monocyte‐derived macrophages and suppressed the production of IL‐6 and CXCL1 in these cells. CSE also decreased microsphere uptake capacity by MDMs. Then, CSE + LPS‐stimulated MDMs were treated with two different JAK inhibitors. AG490 (specific inhibitor of JAK2) and ruxolitinib (inhibitor of JAK1 and JAK2). JAK/STAT inhibitors, particularly ruxolitinib, attenuated in cytokine production without completely inhibiting when compared with dexamethasone. On the other hand, the cells exposed to dexamethasone are nearly unable to capture the microspheres, while both JAK inhibitors do not affect the uptake capacity. In summary, our results showed the versatility of ruxolitinib which might bring a better balance disturbance of cytokine release and uptake capacity. The information regarding the distinctive effect of JAK/STAT inhibitors may be useful in the development of novel treatments for COPD.
Genetic redundancy of 4‐hydroxybenzoate 3‐hydroxylase genes ensures the catabolic safety of Pigmentiphaga sp. H8 in 3‐bromo‐4‐hydroxybenzoate‐contaminated habitats

Published: July 2022

AbstractGenetic redundancy is prevalent in organisms and plays important roles in the evolution of biodiversity and adaptation to environmental perturbation. However, selective advantages of genetic redundancy in overcoming metabolic disturbance due to structural analogues have received little attention. Here, functional divergence of the three 4‐hydroxybenzoate 3‐hydroxylase (PHBH) genes (phbh1~3) was found in Pigmentiphaga sp. strain H8. The genes phbh1/phbh2 were responsible for 3‐bromo‐4‐hydroxybenzoate (3‐Br‐4‐HB, an anthropogenic pollutant) catabolism, whereas phbh3 was primarily responsible for 4‐hydroxybenzoate (4‐HB, a natural intermediate of lignin) catabolism. 3‐Br‐4‐HB inhibited 4‐HB catabolism by competitively binding PHBH3 and was toxic to strain H8 cells especially at high concentrations. The existence of phbh1/phbh2 not only enabled strain H8 to utilize 3‐Br‐4‐HB but also ensured the catabolic safety of 4‐HB. Molecular docking and site‐directed mutagenesis analyses revealed that Val199 and Phe384 of PHBH1/PHBH2 were required for the hydroxylation activity towards 3‐Br‐4‐HB. Phylogenetic analysis indicated that phbh1 and phbh2 originated from a common ancestor and evolved specifically in strain H8 to adapt to 3‐Br‐4‐HB‐contaminated habitats, whereas phbh3 evolved independently. This study deepens our understanding of selective advantages of genetic redundancy in prokaryote's metabolic robustness and reveals the factors driving the divergent evolution of redundant genes in adaptation to environmental perturbation.
Australia's Fiscal Space: The Role of Public Investment
Authors: Domínguez Begoña , Quiggin John 
Published: July 2022

AbstractHow large is Australia's fiscal space? Blanchard (2019) shows that as long as the real interest rate is below the real growth rate , a government can sustain a positive primary deficit with a constant (or even declining) ratio of public debt to GDP. In this article, we explain the neutral real interest rate and the reasons for its decline. Then, we discuss the results of a companion paper, Domínguez and Quiggin (2022), in which we quantify the fiscal space for Australia and find that a permanent increase in the primary deficit can be afforded up to reaching a debt to GDP ratio of 79 per cent. Furthermore, this so‐called ‘free lunch’ in the fiscal space can be expanded if debt is used to finance public investment.
